Tiantai - Tendai zhiguan and the four samadhis (Zhiyi)

1. Introduction

Version followed: Zhiyi's (智顗, 538–597) short manual Xiu xi zhiguan zuochan fayao 修習止觀坐禪法要, known as the Xiao zhiguan 小止觀 ("Essentials for Practising Calming and Insight"), as taught in 2021 by Ven. Chang-Hwa at the Chan Meditation Center (New York; lineage of Master Sheng Yen); the Japanese Tendai sitting method (shikan 止観) as published by Rev. Seishin Clark, a Tendai priest, in A Basic Guide to Tendai Shikan (Tendai UK, 2014), which draws on the Xiao zhiguan, the Liu miao men 六妙門 ("Six Gates to the Sublime") and the Mohe zhiguan 摩訶止觀 (T1911); and the four samadhis (四種三昧) of the Mohe zhiguan as the hall signage of Enryakuji on Mt Hiei and scholarship describe them. Where the Chinese manual and the Japanese Tendai booklet differ, both versions are named.

This is a contemplative practice, not a therapy. Zhiguan renders the Sanskrit śamatha-vipaśyanā: zhi 止 ("stopping", calming) and guan 觀 ("contemplating", insight) [source: Swanson 1991]. In the tradition's own account, calming settles and "subdues" the afflictions (伏煩惱) and builds samadhi, while insight into emptiness "cuts off" the afflictions (斷煩惱); the two must be cultivated in balance, and practice must go together with doctrine, since practice without doctrine is said to lead to misreading one's experiences [source: Chang-Hwa 2021, citing Sheng Yen]. Zhiyi's mature work, the Mohe zhiguan, presents a "perfect and sudden" form of calming-and-insight and teaches that all aspects of reality ("three thousand worlds") are contained, at least potentially, in a single moment of an ordinary person's thought (一念三千) [source: Swanson 1991]. These are the tradition's claims about how liberation happens; they are reported here, not asserted or disputed.

For the psychotherapist: a client may already practise zhiguan, sit in a Tiantai or Tendai temple, chant the Lotus Sutra, or plan an intensive retreat. The therapist's work is to understand the practice as the client's tradition teaches it, support client-led integration with consent, adapt for trauma, watch for adverse effects and scrupulosity, and refer to qualified teachers. The therapist does not teach the practice as a religious teacher [synthesis].

2. Framework

Structure of the Xiao zhiguan (ten chapters) [source: Chang-Hwa 2021]:

The first five chapters give five groups of five preparatory items. In the Mohe zhiguan the "twenty-five skilful means" (二十五方便) form the sixth chapter, the preliminary practice before correct contemplation, which is then set out as ten objects (十境) and ten modes of contemplation (十乘觀法) across scrolls 5–10 [source: Wang Leiquan; the one-to-one correspondence with the Xiao zhiguan chapters is synthesis]. Detail of the ten objects and ten modes is [uncertain: not verified].

The four samadhis (四種三昧). The Mohe zhiguan groups all practice into four outward forms, which can be combined with gradual, indeterminate or perfect-sudden calming-and-insight [source: Wang Leiquan; Swanson 1991]: constantly sitting (常坐), constantly walking (常行), half-walking half-sitting (半行半坐), and neither walking nor sitting (非行非坐). Swanson calls the first a precursor of Zen "sitting-only" and the second a precursor of Pure Land nenbutsu [source: Swanson 1991]. In Japan, Saichō's regulations for students on Mt Hiei made the four samadhis the basic practices of the meditation course of a twelve-year mountain training [source: MLIT Hokke-dō]. See section 4 for each.

Typical format and "dose".

• Lay sitting: a session of shikan is divided between a calming part and an insight part, in equal portions for beginners, once the student is at ease with breath awareness; the steps are to be practised slowly over a long time with a teacher [source: Clark 2014]. No daily frequency is given in that source.
• Intensive monastic retreats: the constantly walking samadhi at Enryakuji's Jōgyōdō is described as a ninety-day practice; the half-walking half-sitting (Lotus) samadhi at the Hokke-dō as a twenty-one-day practice [source: MLIT Jōgyōdō; MLIT Hokke-dō]. These are monastic practices under the Tendai institution, not lay or therapeutic programmes.
• In psychotherapy there is no session count: the practice is the client's, and therapy sessions follow the therapist's own modality [synthesis].

Criteria for moving on (as the sources state them).

• Calming (shi) is the prerequisite for insight (kan) [source: Clark 2014].
• Within breath work, simply following the breath is not recommended for beginners; counting comes first [source: Clark 2014].
• Genuine signs of progress are calm, clarity, faith and keeping precepts; agitation, strange images and emotional disturbance are false signs [source: Chang-Hwa 2021].
• Clinical criterion for any step-up (longer sitting, retreat): stable sleep, no current psychosis or mania, trauma symptoms manageable, client informed of possible adverse effects, and a teacher available [synthesis; adverse-effect data from Lindahl et al. 2017 and Farias et al. 2020].

3. Guiding principles

Tradition principles [source: Chang-Hwa 2021; Clark 2014 unless marked]:

• Calming and insight together. Cultivating samadhi without wisdom, or wisdom without samadhi, is insufficient. Practical meaning: a client who only seeks calm, or only analyses, is not doing zhiguan as taught; ask how their teacher balances the two.
• Practice with doctrine. Experiences are read through teaching. Practical meaning: invite the client to bring their teacher's or text's frame, not yours.
• Release, not suppression, of desire. Practical meaning: watch for clients who turn "reproaching desire" into self-punishment.
• Balance: not too tight, not too loose; neither sinking nor floating. Practical meaning: a familiar language for adjusting intensity when a client is strained or dull.
• Gradual entry and gradual exit. Body, then breath, then mind on entering; mind, breath, body on leaving. Practical meaning: abrupt exits are said to bring sluggishness or headaches [source: Clark 2014]; useful for grounding.
• Regulate daily life first. Food, sleep and lifestyle shape the mind. Practical meaning: sleep and eating are clinical markers too [synthesis].
• Neither fear nor delight in unusual states. Practical meaning: the tradition itself discourages chasing or fleeing experiences; this supports non-pathologising, calm enquiry.
• Practise with a knowledgeable teacher. Unusual and sometimes unpleasant experiences can arise [source: Clark 2014]. Practical meaning: ask whether the client has a teacher, and refer back to them.
• Practice in all activities (歷緣對境). Practical meaning: the practice is not confined to sitting; integration in daily life is the tradition's own aim.

Therapist's principles [synthesis unless marked]:

• Client-led, consented integration. The client decides whether and how their practice enters therapy, in their own language and tradition.
• The therapist is not the teacher. No doctrinal rulings, no assigning tradition practices, no confessor role; refer to the teacher or priest.
• Attribute, do not adjudicate. Mara, karma, emptiness, realms of rebirth are described as the tradition holds them, neither affirmed nor dismissed.
• No health claims. The tradition's chapter on treating illness is respected as belief; physical symptoms go to the client's doctor.
• Safety before depth. Adverse effects occur also in people without psychiatric history [source: Farias et al. 2020]; titrate, ground, and screen before intensive practice.
• Trauma-informed choice. Offer options (eyes open, posture, shorter sits, moving practice) as trauma-sensitive mindfulness recommends [source: Treleaven, via Cheetah House].
• Professional boundaries and competence. Avoid dual relationships (e.g. sitting with the client in the same sangha), manage self-disclosure of your own religious commitments, and work within ethics codes and published spiritual competencies [uncertain: Vieten et al. 2013 not verified; synthesis].

4. Intervention inventory

Part A describes the practices as the tradition openly teaches them, so the therapist can recognise and discuss them; they are taught by the client's teacher, not prescribed by the therapist. Part B is the therapist's own work alongside them. Example language is illustrative throughout.

A1. Fulfilling the conditions and repentance (具緣, 懺悔)

• Purpose / when: The tradition's first preparation: pure precepts, enough food and clothing, a quiet dwelling, laying aside worldly business, good spiritual friends. Where precepts have been broken, repentance: understanding cause and effect, feeling shame, confessing faults, vowing to save beings, and contemplating that wrongdoing has no fixed, arising nature [source: Chang-Hwa 2021]. Relevant when a client speaks of preparing to practise, of guilt, or of repentance rites.
• Steps (as taught, in outline): settle outward conditions; examine conduct; where needed, take part in repentance as the client's temple conducts it, under its teachers [source: Chang-Hwa 2021].
• Example language (illustrative): "Your tradition treats repentance as something that ends in seeing guilt as empty, not in carrying it forever. How does that sit with what you feel now?"
• Watch for: repetitive confession, inability to feel "pure enough" to sit, checking whether precepts were kept: possible scrupulosity (see B7). Working: guilt becomes proportionate and leads to practice rather than avoidance [synthesis].

A2. Reproaching desires and discarding the hindrances (訶欲, 棄蓋, 五停心觀)

• Purpose / when: To loosen attachment to the five sense-desires (release rather than suppress) and remove the five hindrances. The text pairs each hindrance with a "stilling" contemplation: impurity contemplation for greed, loving-kindness and compassion for hatred, causes-and-conditions for ignorance, counting the breath for scattered mind, analysis of the elements for arrogance; recollection of the Buddha is an added option; doubt is met by building trust in oneself, the teacher and the Dharma [source: Chang-Hwa 2021].
• Steps (outline): notice which hindrance dominates; apply the matching contemplation as one's teacher instructs [source: Chang-Hwa 2021].
• Example language (illustrative): "When you sit, which of the hindrances your teacher describes shows up most for you? What has your teacher suggested for it?"
• Watch for: impurity contemplation (contemplating the body as unattractive) in clients with eating disorders, body dysmorphia, sexual trauma or self-disgust; loving-kindness that triggers grief or shame. Discuss alternatives with the teacher [synthesis].

A3. Regulating the five matters (調五事): food, sleep, body, breath, mind

• Purpose / when: To create balance before and during sitting [source: Chang-Hwa 2021].
• Steps (as taught, qualitatively): food moderate in quality and quantity, since overeating brings dullness and undereating instability; sleep regular; body relaxed; breath allowed to become even and fine; mind balanced, correcting "sinking" (dullness) or "floating" (agitation), and tension or slackness. Breath is described in four qualities, from coarse "windy", through uneven and ordinary, to the subtle breath that supports samadhi [source: Chang-Hwa 2021; Clark 2014]. No targets for food or sleep are given here, and none should be prescribed.
• Example language (illustrative): "Your text says to regulate food and sleep before regulating the mind. How have your sleep and eating been this week?"
• Watch for: restriction of food or sleep justified as discipline; insomnia after increasing practice. Route physical concerns to the doctor [synthesis].

A4. Sitting posture and setting (Tendai version)

• Purpose / when: A stable, upright, relaxed body for shikan [source: Clark 2014].
• Steps (as taught): quiet, tidy, airy room; clean loose clothing; optional symbolic rinsing of hands and mouth. Seat options: full or half lotus, Burmese, seiza on a stool, or a firm chair; lying down is discouraged as it invites sleep. Hips above knees; sway gently to find balance; shoulders relaxed, chin slightly tucked; mouth closed, tongue resting on the palate; hands in the meditation mudra on the lap (thumbs pressing = too tense, thumbs parting = too slack); eyes closed or softly open, resting on the floor ahead. Do not force a posture; move or stand if there is pain [source: Clark 2014].
• Example language (illustrative): "Your teacher's guide says not to force the posture. Would a chair make this more workable for now?"
• Watch for: pain endured as virtue; eyes-closed sitting that increases dissociation or flashbacks (offer eyes open) [synthesis; Treleaven via Cheetah House].

A5. Calming (止): three kinds

• Purpose / when: To settle the mind [source: Chang-Hwa 2021].
• Steps (as taught): (1) fixing on an object (繫緣止), resting attention at one place such as the crown, between the brows, the tip of the nose, the navel or the soles of the feet; (2) restraining the mind (制心止), not following thoughts as they arise, especially those driven by the senses; (3) calming that embodies the real (體真止), recognising there is no fixed self to grasp, so the mind settles of itself [source: Chang-Hwa 2021].
• Example language (illustrative): "When thoughts come during your sitting, what does your practice ask you to do with them? Does that feel like letting go, or like pushing down?"
• Watch for: strained suppression of thoughts (rebound, anxiety); interoceptive anchors (navel, breath) that heighten panic in trauma survivors; offer external anchors [synthesis; Treleaven via Cheetah House]. Working: calmer, steadier attention without rigidity.

A6. Breath-based gates: the Six Gates to the Sublime (六妙門)

• Purpose / when: A graded path from calming to insight using the breath: counting, following, stilling, observing (contemplating), returning, and purification [source: Chang-Hwa 2021; Clark 2014].
• Steps (public outline only): Tendai UK teaches beginners to count natural breaths in a short repeating series, restarting whenever a thought intrudes; following the breath without counting comes later and is not for beginners; the breath is then allowed to settle toward the subtle. In the insight phase the breath is contemplated in imaginal form (as light pervading the body) until self, other and breath are seen to dissolve into the Middle, and the mind becomes clear and still [source: Clark 2014]. No breath control, retention, counts or durations are given here; the method is learned from a teacher.
• Example language (illustrative): "When you count the breath, is it just noticing, or do you find yourself controlling it? Your teacher may want to hear about that."
• Watch for: breath focus provoking panic, air hunger or trauma memories; imaginal "light" practices producing intense somatic or energetic sensations. Switch to non-breath anchors and consult the teacher [synthesis; Lindahl et al. 2017].

A7. Insight (觀): contrary and correct contemplation

• Purpose / when: Wisdom that sees all phenomena as arising from causes and conditions and lacking intrinsic nature [source: Chang-Hwa 2021].
• Steps (as taught): contrary or counteracting contemplation (對治觀) uses a specific contemplation against a specific affliction; correct contemplation (正觀) sees the true character of reality (實相): because all dharmas arise from conditions without fixed nature, the observing mind itself comes to rest [source: Chang-Hwa 2021]. In the Mohe zhiguan, contemplation of the mind is elaborated through ten objects and ten modes [source: Wang Leiquan]; the threefold contemplation of emptiness, the conventional and the middle is reflected in the Xiao zhiguan's final chapter (entering emptiness from the conventional, the conventional from emptiness, and the Middle Way) [source: Chang-Hwa 2021].
• Example language (illustrative): "When you look at a painful thought the way your practice teaches, as arising from conditions, what changes in how it feels?"
• Watch for: depersonalisation, derealisation or nihilistic despair presented as "seeing emptiness"; spiritual bypassing of grief or conflict. Explore function and distress without disputing doctrine [synthesis; Lindahl et al. 2017].

A8. Remedies within sitting

• Purpose / when: To correct coarseness and scatter, sinking, floating, and attachment to the joy of subtle samadhi, and to keep samadhi and wisdom in balance [source: Chang-Hwa 2021].
• Steps (outline): when dull, brighten attention; when agitated, settle it; when attached to pleasant states, release them; rebalance calming and insight [source: Chang-Hwa 2021; specific remedies are taught by the teacher].
• Example language (illustrative): "Your tradition warns against getting attached even to blissful states. Have the pleasant states become something you chase?"
• Watch for: craving for absorptive states, increasing practice to regain them, sleep loss [synthesis].

A9. Calming and insight in daily activity (歷緣對境)

• Purpose / when: Extending practice to walking, standing, sitting, lying, speaking and working, and to every meeting of sense and object [source: Chang-Hwa 2021].
• Steps (as taught): before acting, ask what one's intention is and refrain from harmful action; in calming, see the act and the actor as ungraspable; in insight, see the walker and the walking as empty; meet pleasant, unpleasant and neutral feelings without grasping, rejecting or ignoring [source: Chang-Hwa 2021].
• Example language (illustrative): "Your practice asks you to pause and check your intention before acting. Could that be part of how you handle the argument you described?"
• Watch for: constant self-monitoring of intention becoming obsessive checking (see B7). Working: values-based pauses that reduce reactivity [synthesis].

A10. Leaving sitting gradually

• Purpose / when: To return to ordinary activity without disturbance [source: Chang-Hwa 2021; Clark 2014].
• Steps (as taught): release from the subtle mind to ordinary mind, then breath, then body; gently move fingers, toes, head and shoulders, rub the hands and the eyes, massage the legs, then stand and stretch. Improper exit is said to cause clouded mind, sluggishness or headaches [source: Clark 2014; Tendai UK also opens the mouth and breathes out deeply, given here only qualitatively].
• Example language (illustrative): "Your guide describes coming out slowly. Let's use that same sequence now, before you leave the session."
• Watch for: feeling spaced-out or unreal after sitting; use this as a grounding routine in session [synthesis].

A11. Signs of good roots and recognising Mara (發善, 覺魔)

• Purpose / when: The tradition's own discernment of experiences in practice [source: Chang-Hwa 2021].
• What the tradition teaches: outward good roots (generosity, precepts, respect for teachers, study) and inward ones (calm, luminous states; strong bodily sensations, including the "sixteen tactile sensations"; visions). Genuine signs bring calm, clarity, faith and precept-keeping; false ones bring agitation, strange images and emotional disturbance. Four kinds of Mara are named: of the afflictions, of the aggregates, of death, and of gods or spirits. The response is to remain undisturbed and not cling (calming), examine whether perceiver and perceived truly exist (insight), neither fear nor delight, recite scriptures and mantras, repent, and learn from experienced teachers [source: Chang-Hwa 2021]. Mara and spirits are the tradition's categories, reported here, not asserted or dismissed.
• Example language (illustrative): "In your tradition's terms, does this feel like a genuine sign or a disturbance? And separately, how are your sleep, mood and daily functioning?"
• Watch for: voices, persecutory beliefs, grandiosity, sleep loss, inability to function: assess for psychosis or mania alongside the tradition's frame (see B5) [synthesis].

A12. The chapter on treating illness (治病)

• What the tradition teaches: illness in practice is attributed to imbalance of the elements and organs, to spirits, or to karma; remedies include resting the mind at the affected place or the lower abdomen, six named breath-sounds linked to organs, visualisation, recognising the body and the illness as ungraspable, together with medicine and exercise, mantras, and repentance and merit [source: Chang-Hwa 2021]. No technique is given here.
• Evidence status: these are religious claims; there is no clinical evidence here that these methods treat physical disease [synthesis].
• Example language (illustrative): "Your text has its own understanding of illness. Alongside that, has a doctor looked at these symptoms?"
• Watch for: delaying medical care; replacing prescribed treatment. Never advise on medicines; route to the client's doctor [synthesis].

A13. The four samadhis (四種三昧)

• Purpose / when: The Mohe zhiguan's four outward forms that together encompass Buddhist practice [source: Swanson 1991; Wang Leiquan]. Relevant when a client attends or plans a Tendai or Tiantai intensive.
• Constantly sitting (常坐三昧): sustained seated samadhi; described as a precursor of Zen sitting-only [source: Swanson 1991]. Further detail (setting, period) [uncertain: not verified].
• Constantly walking (常行三昧, J. jōgyō zanmai): at Enryakuji's Jōgyōdō, enshrining Amida, practitioners chant Amida's name and concentrate on him while walking within the hall for ninety days without rest, not lying down; those who reach deep concentration are said to see the Buddha before them, hence the name "Buddha-standing samadhi" (butsuryū zanmai). The hall is still used [source: MLIT Jōgyōdō]. This is a monastic austerity involving severe sleep restriction; described here qualitatively, never as a model for clients.
• Half-walking half-sitting (半行半坐三昧): at the Hokke-dō, enshrining Fugen (Samantabhadra), practitioners combine full prostrations in worship and repentance, walking around the hall reciting the Lotus Sutra, and seated meditation, over twenty-one days, aiming to receive the Buddha's wisdom [source: MLIT Hokke-dō]. Lay Tendai practice includes walking-and-sitting Lotus repentance (Hokke senbō) with Lotus Sutra chanting [source: Clark 2014].
• Neither walking nor sitting (非行非坐三昧): calming-and-insight in any activity, also called "samadhi following one's own mind" (隨自意三昧) [source: Chang-Hwa 2021]. Sitting remains the best entry [source: Chang-Hwa 2021].
• Example language (illustrative): "Tell me what the retreat will ask of you each day, in your teacher's words. Then let's look together at your sleep, health and support while you're there."
• Watch for: sleep deprivation, exhaustion, injury from prostrations, isolation, re-emergence of trauma, manic or psychotic decompensation during or after intensive practice; route physical concerns to the doctor and screen beforehand (B4) [synthesis; Lindahl et al. 2017].

A14. Liturgy and chanting

• Purpose / when: Chanting the Tendai liturgy is taught as a way to change mind and habits, arouse the aspiration to awakening (hotsu bodaishin) and acknowledge past wrongdoing [source: Clark 2014].
• Steps: as the temple teaches; not reproduced here.
• Example language (illustrative): "When you chant, what happens to the worry you brought in? Is the chanting a support right now, or has it become something you have to get exactly right?"
• Watch for: compulsive repetition or fear of error in recitation (B7). Working: chanting is experienced as steadying and connecting [synthesis].

B1. Spiritual assessment and consent to integrate

• Purpose / when: At intake, or when a client mentions zhiguan, shikan, a temple or a retreat.
• Steps: (1) ask what they practise, which text or teacher, which temple or lineage (Chinese Tiantai, Japanese Tendai, a Chan centre teaching Zhiyi); (2) ask frequency, intensity and any planned retreat; (3) ask what the practice means to them and what role they want it to have in therapy (none, background, active resource); (4) record consent and its limits; (5) cultural formulation, for example with the DSM-5-TR Cultural Formulation Interview and its supplementary module on spirituality, religion and moral traditions [uncertain: not verified; synthesis].
• Example language (illustrative): "Some people want their meditation kept separate from therapy, others want to draw on it. What would feel right for you?"
• Watch for: a client who feels the therapist is judging or appropriating the practice; reluctance to mention unusual experiences for fear of being pathologised [synthesis].

B2. Client-led integration in spiritually integrated psychotherapy

• Purpose / when: When the client wants their practice used as a resource.
• Steps: (1) let the client name the teaching that helps (e.g. regulating the five matters, not too tight nor too loose, gradual exit, pausing to check intention); (2) link it to the therapy goal in their words; (3) agree how they will use it between sessions, as their teacher teaches it; (4) review effects, including unwanted ones [synthesis]. Cross-refer Domain VII (contemplative and Buddhist psychotherapy; spiritually integrated psychotherapy).
• Example language (illustrative): "You said your teacher talks about balancing calm and clear seeing. What would that balance look like in how you handle this week's stress?"
• Watch for: therapist drifting into teaching doctrine; client using practice to avoid painful material. Working: client reports the practice supports rather than replaces emotional processing [synthesis].

B3. Secular and clinical adaptations

• Purpose / when: When the client wants a non-religious or clinically structured form.
• What exists: no published clinical protocol specific to Tiantai zhiguan is cited here [uncertain: not verified]. Related secular programmes: Domain II (MBSR, MBCT, MSC, CFT) for attention, decentring and compassion training; Domain IV (trauma-sensitive yoga) for body-based, choice-led work; Domain VII for contemplative and Buddhist psychotherapy [synthesis].
• Steps: discuss whether a secular programme suits; if the client keeps their Tiantai or Tendai practice too, keep the two clearly distinguished, and do not strip religious content from the client's own practice without their wish [synthesis].
• Example language (illustrative): "There are secular courses that share some methods with your practice. Would that be useful alongside your temple practice, or would it feel like a dilution?"
• Watch for: confusion between programme instructions and the teacher's instructions [synthesis].

B4. Screening before intensive practice or retreats

• Purpose / when: Before a client starts longer sittings, a sesshin-style intensive, or one of the four samadhi retreats.
• Steps: review current and past psychosis, mania or bipolar disorder, severe depression and suicidality, PTSD and dissociation, substance use, sleep problems, physical health conditions affected by sitting, walking, prostration or sleep loss (route to the doctor); discuss that challenging experiences are documented, last from days to years in some cases, and can occur without prior psychiatric history; agree warning signs and a plan (who to contact, permission to stop, how to reach the teacher) [source: Lindahl et al. 2017; Farias et al. 2020; synthesis for the checklist].
• Example language (illustrative): "Research with long-term meditators shows that difficult experiences such as anxiety, insomnia or feeling unreal sometimes come up. It doesn't mean something's wrong with you. Let's plan what you'd do if it happened."
• Watch for: pressure from the group to attend despite risk; the client hiding symptoms to be accepted [synthesis].

B5. Telling spiritual crisis apart from illness

• Purpose / when: When unusual perceptions, energy, visions, "Mara" experiences, loss of self or intense fear arise.
• Steps: (1) hear the experience in the client's own frame (good roots, Mara, emptiness) without dismissing it; (2) assess functioning, sleep, insight, safety, psychotic or manic features, dissociation and depression; (3) where criteria for a mental disorder are not met, the DSM-5-TR category Religious or spiritual problem (Z65.8) can be recorded; (4) where illness is present, treat or refer while respecting the frame; (5) with consent, consult the teacher [synthesis; categories of experience from Lindahl et al. 2017].
• Example language (illustrative): "Your tradition has a way of understanding this, and I want to respect it. I'd also like to check some things about sleep, mood and safety, because these experiences can sometimes need extra support."
• Watch for: the documented domains of meditation-related challenges: cognitive, perceptual (e.g. light or sound hypersensitivity), affective (fear, panic, loss of emotion), somatic (insomnia, involuntary movements), conative, sense of self, social [source: Lindahl et al. 2017]; prolonged states of oneness that impair work [source: Lindahl et al. 2017].

B6. Trauma-sensitive adaptation, dose reduction and grounding

• Purpose / when: For trauma survivors, or anyone whose practice is producing hyperarousal (anxiety, insomnia, intrusive thoughts, involuntary movements) or dissociation (emotional flattening, loss of meaning, derealisation) [source: Cheetah House].
• Steps: (1) normalise: challenges are not necessarily the person's fault [source: Lindahl et al. 2017, via Brown University]; (2) with the teacher's agreement where possible, reduce dose: shorter or fewer sittings, pause retreats; (3) shift anchors: eyes open, external sounds or the feet rather than breath or the abdomen; movement practice rather than stillness; (4) grounding: use the tradition's own gradual-exit sequence (A10), orienting to the room, contact with the floor; (5) support sleep, food and social contact, echoing the tradition's "regulating the five matters"; (6) consider specialist support, for example Cheetah House consultations (not for acute crises) [source: Cheetah House; Treleaven Trauma-Sensitive Mindfulness, recommended by Cheetah House; steps 2–5 synthesis].
• Example language (illustrative): "Your own tradition says not to force the posture and to come out of sitting slowly. Let's apply that same care now: what would a smaller, gentler amount of practice look like?"
• Watch for: client fears that reducing practice is spiritual failure; symptoms persisting after stopping (escalate assessment). Working: arousal settles, sleep returns, client can sit briefly without flooding [synthesis].

B7. Scrupulosity around precepts, repentance and recitation

• Purpose / when: When repentance, precept-keeping, recitation or intention-checking becomes repetitive, fear-driven and impairing.
• Steps: (1) assess: rituals that mimic religious practice, such as excessive confession or prayer, consuming time and interfering with practice and life; OCD is ego-dystonic while healthy practice is ego-syntonic [source: IOCDF]; (2) psychoeducation: ERP is first-line for scrupulosity and aims to strengthen values, not violate faith; uncertainty is part of faith [source: IOCDF]; (3) with consent, consult the client's teacher or priest on what the tradition actually requires, and design exposures within that (e.g. stopping repentance once as the temple prescribes rather than repeating it; tolerating doubt about whether a precept was kept) [source: IOCDF on clergy collaboration; specific exposures synthesis]; (4) agree exposures collaboratively, starting low, never requiring acts the client experiences as genuinely violating their faith; contraindications: active psychosis or acute suicidality [synthesis].
• Example language (illustrative): "Your teacher said one repentance is enough. The urge to repeat it is the OCD talking. Shall we practise letting the doubt be there without repeating?"
• Watch for: reassurance-seeking from the therapist or teacher; clergy who attribute OCD to weak practice [source: IOCDF]. Working: less time on rituals, practice feels freer [synthesis].

B8. Referral to and collaboration with teachers and priests

• Purpose / when: For questions of doctrine, method, retreats, ordination or ritual; when experiences arise in practice; when the client wants coordination.
• Steps: (1) identify a qualified teacher in the client's own lineage (a Tendai priest, a Tiantai monastic, a Chan centre teacher); (2) obtain written consent and agree what is shared; (3) ask about the teacher's guidance and any adjustments; (4) keep clinical decisions with the clinician and doctrinal ones with the teacher [synthesis; teacher guidance recommended by Clark 2014].
• Example language (illustrative): "Would it help if I spoke with your teacher about adjusting your practice while things are difficult? You decide what I share."
• Watch for: teachers who discourage mental-health care; a client without any teacher self-teaching intensive methods from books [synthesis].

B9. Teacher relationship, power and leaving a group

• Purpose / when: Where the client's relationship with a teacher or community involves dependence, secrecy, exploitation or distress, or after leaving.
• Steps: (1) explore the relationship's benefits and costs without judgement; (2) look for signs of coercive control: isolation from family and outside advice, demands for unquestioning obedience, financial or sexual exploitation, punishment for doubt, discouraging medical or psychological care [synthesis]; (3) support autonomy and informed choice; (4) for those who leave, address loss of community, identity and meaning, and any religious trauma; Cheetah House lists religious and systemic trauma among its resources [source: Cheetah House]. No independent investigation concerning Tiantai or Tendai teachers is cited in this guide.
• Example language (illustrative): "What does your teacher's role in your life feel like now? Are there things you feel you can't question?"
• Watch for: safeguarding duties where abuse is disclosed; dual relationships if therapist and client share a community [synthesis].

B10. Keeping the therapist's role

• Purpose / when: Throughout.
• Steps: do not act as meditation teacher, confessor or spiritual director; do not perform repentance or blessings; reflect on your own religious commitments and disclose only for the client's benefit; work within your ethics code and published spiritual and religious competencies [uncertain: Vieten et al. 2013 not verified; synthesis].
• Example language (illustrative): "I can help with what's happening emotionally; questions about the right way to practise are best taken to your teacher."
• Watch for: the client asking for doctrinal rulings or recommending the therapist join their temple [synthesis].

5. Handling problems

The tradition's own remedies are cited; all clinical responses are [synthesis] unless a source is named.

• "I can't calm my mind; I'm failing." The Xiao zhiguan expects scatter and sinking and gives remedies, and offers different calming methods for different minds [source: Chang-Hwa 2021]. Response: normalise; ask what the teacher suggested; check whether the client is over-straining ("too tight"). Illustrative: "Your text expects the mind to wander and has remedies for it. Struggle isn't failure in its terms."
• Stuck in calm, avoiding feelings (bypassing). The tradition warns against attachment to the joy of samadhi and insists on balancing calm with insight [source: Chang-Hwa 2021]. Response: use that teaching to invite engagement with avoided material; agree that practice supports, not replaces, emotional work.
• Overwhelm, panic or flashbacks during sitting. Response: stop or shorten; eyes open; external anchors; gradual-exit sequence; review trauma history; consider trauma-sensitive adaptation (B6) and Cheetah House resources; involve the teacher with consent [source: Cheetah House; Lindahl et al. 2017 for the phenomena].
• Symptoms that persist after reducing or stopping practice. Difficulties can last months or longer [source: Lindahl et al. 2017]. Response: full assessment for depression, anxiety, dissociation, psychosis; refer for medical review; specialist consultation.
• Experiences framed as Mara, spirits or karma. Response: hold both frames: the tradition's (neither fear nor delight; examine; consult teachers [source: Chang-Hwa 2021]) and the clinical (risk, sleep, function). Do not argue doctrine; escalate if psychotic or manic features appear.
• Retreat pressure despite risk. Response: share screening concerns honestly; offer to speak with the teacher; respect the client's decision while agreeing a safety plan; never present the austerities (sleep restriction, prostrations, prolonged walking) as clinically safe; route physical questions to the doctor.
• Non-adherence to their own practice. The practice is the client's, not homework from the therapist. Response: explore meaning (guilt? loss of faith? burnout?) rather than pushing practice; refer doctrinal questions to the teacher.
• Scrupulosity disguised as devotion. Response: assess ego-dystonic fear and time cost; ERP with clergy consultation (B7) [source: IOCDF].
• Rupture: the client feels the therapist is secularising, dismissing or appropriating their tradition. Response: acknowledge; ask how they want the practice handled; correct any doctrinal misstatement by deferring to their teacher.
• Rupture: the therapist is idealised as a teacher. Response: name the role boundary (B10); redirect spiritual guidance to the teacher.
• Conflict between teacher's advice and clinical advice (e.g. "sit through it" versus reducing dose). Response: with consent, consult; explain the documented adverse-effect evidence [source: Farias et al. 2020]; client decides; document risk discussion.
• Health beliefs from the chapter on treating illness replacing medical care. Response: respect the belief, state plainly that physical symptoms need a doctor; no advice on medicines.
• Concerns about a teacher's conduct. Response: explore, look for coercive-control signs, follow safeguarding and reporting duties; name no one as a wrongdoer unless an independent investigation, court, regulator or major news outlet has done so.
• Client wants the therapist to teach Tiantai meditation. Response: decline the teacher role; refer to a temple or recognised teacher, or offer a secular programme if clinically indicated (B3).
