What This Concept Is Actually Saying
If you ask a contemporary working person "do you practice?" they will probably think you mean yoga, meditation, or hitting the gym. In the canonical sources, 修行 (xiūxíng) is far more ordinary and far more demanding than any of those. 增壹阿含經 (Ekottara Āgama) is the most unadorned: 修行 is the repeated, sustained reshaping of what you do, what you say, and what you attend to — the terminal point in that text is rendered as 泥洹證 (nirvāṇa, using this Āgama's transliteration). "Reshaping" here is not a metaphor for inner growth; it is concrete — not killing, generosity and供養, sitting in dhyāna and examining what has been heard, "聞法辨義" (hearing the dharma and discerning its meaning), "不放逸" (non-negligence), and "慈心" (maitrī / loving-kindness) extended to all beings.
But 修行 is not a single thing. Across the sutras and śāstras the word unfolds into several distinct yet interlocking layers. Walking through them faithfully is the only way to do it justice.
The first layer — 修 = 常行積集. 大智度論 (Mahāprajñāpāramita-śāstra) defines 修 simply as "常行積集" — continuous practice and accumulation. So 修行 is not a single heroic act; it is the patient, repetitive, often unglamorous work of showing up. 增壹阿含 keeps repeating the same grammatical shape — 修行已、多修行已 ("has practiced, has practiced much"), 當念修行 ("constantly remember to practice"), 常當修行而不放逸 ("always practice without slackening"). The emphasis falls on duration and remembering, not intensity.
The second layer — even a milk-squeezing moment counts. 雜阿含經 (Saṃyuktā Āgama) gives one of the most quoted passages in the entire canon on practice: "善男子、善女人若不能數數修習慈心，便為惡鬼神所欺；若能數數修習，即使短至如擠牛乳頃，亦不為惡鬼神所欺。" — if you cannot 數數修習 ("repeatedly cultivate") loving-kindness, you will be deceived by malevolent spirits; if you can 數數修習 it, even for the time it takes to squeeze milk from a cow's udder, you will not be. The佛 adds that even a finger-snap of repetition works, with the image of 佛爪土 (the soil on the Buddha's fingernail) versus 大地土 (all the soil of the earth) — those who can manage even such brief repetitions are rare. The implication: stop waiting for the perfect hour, the retreat, the spacious day. If your hands are squeezing, your mind can be cultivating.
The third layer — practice has substance; it is not a word for "being spiritual." Across traditions it has content: - 增壹阿含: 不殺生, 布施供養, 坐禪思惟, 聞法辨義, 不放逸, 斷漏. - 大方等大集經 (Mahāvaipulya Mahāsannipāta Sūtra): 修身 → 修心 → 修慧, and the six 波羅蜜 (pāramitā / perfections) in transliterated form: 檀 dāna, 尸 śīla, 羼提 kṣānti, 毘梨耶 vīrya, 禪 dhyāna, 般若 prajñā. - 大乘起信論 (Treatise on the Awakening of Faith, Paramārtha's translation): five gates — 施 (dāna / giving), 戒 (śīla / precepts), 忍 (kṣānti / patience), 進 (vīrya / vigor), 止觀 (śamatha-vipaśyanā / calm abiding and insight).
Note that what counts is the fullness of the practice, not the moment-of-insight alone.
The fourth layer — how 修行 differs from 戒 and 施. 俱舍論 (Abhidharmakośa) makes a sharp and useful cut. All three — generosity, precepts, cultivation — are 福業事 (meritorious conduct), but each has its own fruit. The treatise defines 修 as "等引善, 極能熏心故" — 修 is "samādhi-bringing goodness, because it intensely pervades the mental continuum." Generosity ripens in pleasant conditions; precepts (戒) at their best yield rebirth in the heavens (戒勝感生天); cultivation (修) at its best yields liberation (修勝感解脫). So 修 is distinguished by the depth with which it pervades the mind-stream — not by effort, but by transformative depth.
The fifth layer — the technical heart: 奢摩他 and 毘鉢舍那. 瑜伽師地論 (Yogācārabhūmi-śāstra) gives the most systematic formulation: 修習 is "住於彼勤修二法, 謂奢摩他、毘鉢舍那" — dwelling diligently in two methods, namely 奢摩他 (śamatha / calm abiding) and 毘鉢舍那 (vipaśyanā / penetrative insight). They work in alternation: 已習奢摩他 "依毘鉢舍那" 得解脫 of 見所斷煩惱 (defilements cut at the path of seeing); 已習毘鉢舍那 "依奢摩他" 得解脫 of 修所斷煩惱 (defilements cut through cultivation). The fruits are 三界 — 斷界 (the realm of cutting), 離欲界 (the realm of dispassion), 滅界 (the realm of cessation). The same treatise distinguishes 四種修 (four kinds of cultivation): 得修 (acquired cultivation), 習修 (habitual cultivation), 除去修 (cultivation of removal), 對治修 (antidotal cultivation). It reduces these to 二種修: 防護受持修 (protective cultivation: 修身 and 修戒) and 作意思惟修 (thoughtful cultivation: 修心 and 修慧). And it sits these on three levels — 世間修 (worldly cultivation), 有學修 (cultivation while still in training), 無學修 (cultivation of the adept beyond training). This is the most granular classical anatomy of how 修行 actually operates.
The sixth layer — 修行 is inseparable from 聞法 (hearing and studying dharma). 大寶積經 (Mahāratnakūṭa Sūtra) hammers the link in many forms: 聞已常憶持, 復如法修行 (having heard, always remember, and further practice in accordance with the dharma); 如法修行 (practice in accordance with dharma); 如說修行 (practice as taught). And then it makes the hard warning: "若但言說住於放逸而不修行, 彼尚不能至聲聞地, 何況能得阿耨多羅三藐三菩提" — if one merely talks and dwells in indulgence and does not 修行, one cannot even reach śrāvaka-stage, much less anuttarā-samyak-saṃbodhi. 〈妙慧童女會〉 condenses it: 發言修行常使相應 — speech and practice must always correspond. This is the most-quoted ancient warning against the modern disease of mistaking exposure to dharma for cultivation of dharma.
The seventh layer — 熏習, the mechanism that explains why repetition works. 大乘起信論 opens up the inside-the-mind story that the other texts only imply. The mechanism is 熏習 (xúnxí / "perfuming," i.e., repeated mutual conditioning). Two opposite currents run in parallel. The 染法 side: 妄境界 has 增長念熏習 and 增長取熏習; 妄心 has 業識根本熏習 and 增長分別事識熏習; 無明 has 根本熏習 and 所起見愛熏習. The 淨法 side: 真如法熏習無明, which makes the deluded mind tired of samsāra's suffering, seek nirvāṇa, and engage in 修遠離法 ("practice of distance-from-attachment"), culminating in 不取不念 (no grasping, no internal marking) — only after 經久遠熏習 does 無明 go out, mind not arise, and objects dissolve. 修行 on this account is not a single willful act but a slow mutual-conditioning in which the pure tendency gains ground by patient repetition. (A contemporary parallel: the way large language models are trained by repeated exposure to a corpus — input shape output shapes input — is structurally similar to 熏習. But the analogy is partial: a trained model has no 等引善, no 涅槃 as a goal, no capacity for 慈心. The similarities are about surface process; the differences are about orientation and end.)
The eighth layer — the deep paradox: 無相無行. The 勝慧菩薩問修行大法光明 chapter of 大寶積經 makes the sharpest move: bodhisattva-mahāsattvas practice "無少修行, 無勝修行, 不隨修行, 不遍修行... 一切行息所行清淨得法光明" — no minimal cultivation, no superior cultivation, no following cultivation, no all-pervading cultivation; when every doing ceases, the conduct being done is pure, and the great dharma-light is obtained. The text then names it: 捨一切行無所執取 (letting go of all doing, not grasping at anything), 非數量行、非隨相行、無相無行 (not quantified doing, not "following characteristic" doing, unconditioned and without doing). This is not a repudiation of effort; this is the point at which the figures for "effort" themselves begin to fall away. Hīnayāna and basic Mahāyana修行 proceed through repeated, intensified, comprehensive, condition-following cultivation. The ābhisamaya-level practice refuses all four of those adjectives — and is therefore called 修 as well, only now it is 修 as 真如之修, 修 as 無所住.
The ninth layer — Chan/Zen's re-vision of修行. The Chan tradition takes the hardest question — does an awakened person still need to cultivate? — and refuses to choose.
溩山靈祐 (Mazu, in the line of the Tang Chan lineages) answers in three moves that everyone serious about修行 eventually has to sit with:
1. 破執 (cutting through attachment): "若真悟得本, 他自知時, 修與不修, 是兩頭語" — if one has truly awakened to the root, one knows it oneself; 修 and 不修 are both 两頭語 (two-sided language). 2. 立義 (defining): "初心... 無始曠劫習氣, 未能頓淨, 須教渠淨除現業流識, 即是修也" — for a beginner, although there has been a sudden insight, the 習氣 (latent habitual tendencies) of beginningless eons cannot be purified all-at-once; you must teach them to 淨除現業流識 (purify the currently-flowing karmic consciousness). That itself is what is called 修. 3. 總攝 (integrating): "實際理地, 不受一塵; 萬行門中, 不捨一法... 即如如佛" — in the ground of actual principle, not a single speck of dust is accepted; in the gateway of myriad practices, not a single dharma is abandoned. If one cuts in directly, the feelings of ordinary and saint are exhausted, the substance is revealed as always-so, principle and practice are non-dual — 即如如佛 (this itself is the thusness-buddha).
So Chan does not discard修行 and does not simply keep修行: awakened mind sees through "修" as a self-project, and at the same time restores ordinary life as 修 — moment-by-moment purification of currently-flowing karmic consciousness.
洞山良价's last-words phrase condenses the whole Chan re-vision into ten characters: "心不附物, 是真修行" — the mind not clinging to objects is true practice. The word 真 distinguishes it from 妄 (counterfeit) practice.
古尊宿語錄 then takes the next step: 直下修行 ("straightforward practice right here"), 解修行即得 ("understand [the matter of] practice and you've got it"), 妙用而不住 ("wondrous function without abiding"), and — most scandalously to religious sentimentality — 着衣喫飯 (wearing clothes, eating rice) is named 正大修行 ("proper, vast practice"). The point is not anti-ritual; the point is that the site of cultivation has moved from the temples-and-ceremonies setting into the everyday body-mind.
The single most famous accessible line on修行 for laypeople comes from 六祖壇經: "若欲修行, 在家亦得, 不由在寺" — if you wish to cultivate, you can do it as a householder; it does not depend on being in a monastery. 修行's location is not the temple, not the robes, not the title — it's the mind worked on. The same text adds the corresponding positive formulation: "但心清淨, 即是自性西方" — a mind that is just-pure is itself the Pure Land.
So 修行, when you put all the layers together, is one word that names an entire hierarchy: the milk-squeezing-length repetition of loving-kindness, the milk-squeezing-length sitting in śamatha, the lifelong systematic calm-and-insight, the gradual conditioning of mind by mutual perfuming, the bodhisattva's letting-go-of-every-project, the householder's just-eating-rice. The single Chinese character 修 is the binder: in 俱舍論 it means 等引善 — samādhi-bringing goodness that pervades mind — and in 大智度論 it means 常行積集 — continuous accumulating. Both are essential. A momentary 等引善 without 常行積集 doesn't pervade; a long 常行積集 without 等引善 saturates with noise. 修行 is the place where depth and duration meet.
Life's Audit
Walking the concept through a few ordinary scenes will make the layers stop being abstract.
Scene 1 — the morning phone spiral. You wake up and "just check" your phone. Twenty minutes later you're lost in feeds, body tense, schedule already compressed. Where does 修行 begin?
By 增壹阿含's 數數修習 even a milk-squeezing moment counts, the practice is not throwing the phone away but inserting one breath before unlocking. Each morning. That's the basic rep.
By 大方等大集經's 修身→修心→修慧 order: first 修身 — change posture, set the phone down, sit upright for ten breaths. This is bodily practice that supports the next step. Then 修心 — notice the pull of the feed. Not fight it; just notice. This is the 因熏習 / 淨法熏習 work of 起信論: every unattended scroll is a 染法 rep of the 增長念熏習 kind; every noticed moment is a small reversal in the same mechanism. Then 修慧 — ask, "what am I actually hungry for?" The morning spiral is rarely about information; it's about avoiding the threshold of the day.
The mistake people commonly map here is to assume修行 means willpower-self-denial. No: it means refusing the default — what the Āgama calls 念修行, "practicing with remembering."
Scene 2 — workplace speech-and-action split. You write a beautiful memo about psychological safety or kindness culture. Then you return to your desk and sharply cut a junior in front of others. 大寶積經 〈文殊師利說般若〉 is the scripture that fits this scene precisely: 言說 vs 修行 (talk vs cultivates). 〈妙慧童女會〉's principle: 發言修行常使相應 (speech and practice must always correspond). 起信論's 戒門 lists not just the external restraint but the inner — don't internally rehearse the cutting speech. The 忍門 adds: also endure 利衰毀譽稱譏苦樂 — gain and loss, defamation and praise, blame and acclaim, suffering and pleasure.
But the Chan caution applies too: 修行 is not "become a passive pushover." 瑜伽師地論's 對治修 is named that because the practice is specifically an antidote to a particular poison. With the junior, the antidote is not silence but a different kind of speech. Walking it through — breath, body, choice, words — is the 修. The right reading of this scene is closer to 俱舍論's reframing: the actual 修 is the moment-of-pervading-goodness, not the speech about goodness.
The misreading the Āgama specifically wards against: treating the memo as the practice. 增壹阿含 directly warns kings: don't 修行其惡 under cover of piety. The substance of practice is what you do when no one is watching.
Scene 3 — parenting / close relationship, the 慈心 moment. 雜阿含's specific practice: 修習慈心 toward 一切眾生. At home this is hardest with the people closest, because they're the ones most likely to make the 心附物 (mind cling to objects/people). 雜阿含 offers the 匕手劍 image (a sword of broad, sharp blade) — the cultivated loving-kindness is a surrounding protection. The point is 數數 — parents who cultivate this don't do it once at a retreat; they do it at 2 a.m. when the child is sick and again the next morning when the child refuses shoes.
The contemplative layer, 修行禪思者, has what 雜阿含 describes as "熾焰金色身" (a blazing golden-body) — not a literal body of light but a mind so present it radiates. Parents who learn to be fully present for five minutes at a time are training this without knowing the technical name.
The misreading here is the most relational one: thinking修行 of kindness is the same as never being angry. 起信論's 忍門 is more honest — the work is to 忍 (endure, bear) without internal retaliation, and to keep going back to the kind intention each time.
Scene 4 — the wellness-spirituality consumer. You have read ten books on meditation. You have a meditation app with a streak. You can talk fluently about emptiness. 大寶積經 is the scripture for this scene: 若但言說住於放逸而不修行 — if you dwell in indulgence and only talk. 壇經's "依偈修行" line is pointed at exactly this: it's not whether you've heard the teaching, it's whether you 依 this — let it become the actual ordering of your body-mind. 起信論's analysis is especially useful: lots of reading-without-practicing is 增長念熏習 — the mind is being perfumed by the words, but not the words as practice; so the perfuming is essentially the same shape as the defiled kind, just with nicer content. The threshold is whether you sit down, even briefly, and notice what's actually happening.
The misreading is the most modern one: mistaking information for transformation. 攝大乘論's 數習生 says it's the 數習 — the repeated practical training — that produces 加行無分別智 (preparatory non-discriminating wisdom), not the accumulation of dharma-talk. Contemporary readers can imagine the same way you don't learn piano by reading about it; you 修 it.
Scene 5 — the inner cynicism / "I've been through this." The seasoned practitioner, or the ex-practitioner, who shrugs "nothing much happens." 溩山 speaks to this case most directly — the beginner who says "I've already had the awakening insight, what more is there to 修?" 溩山: 初心, 無始曠劫習氣, 未淨, 須淨除現業流識, 即是修也. 修 is not the seeking of new insight; it's the patient work of letting current conditioning drain. 洞山's 真修行 depends on the existence of 妄修行 — there is a counterfeit — and the lie detector is 心附物 / 不附物.
The misreading is the belief that修行 is a self-improvement curve; in fact the deepest layer of修 is the uncurving of the curve. 瑜伽師地論's third grade of cultivation — 無學修 (adept cultivation) — is described as 心堅固安住, 都無一切下至失念 (the mind solid and at rest, altogether without even momentary lapses of mindfulness). That's what patient 淨除 flows toward.
Why Contemporary People Need This
We live in an era that rewards information accumulation and prestige display, and that quietly penalizes the slow, inward, repetitive labor of self-transformation. The drift from修行 to talking-about修行 is not invented by modern culture — 大寶積經 is warning against it in the first millennium — but it has been massively amplified by social media, attention markets, and the wellness-industrial complex. 修行, as the canonical texts frame it, is the antidote to three specific contemporary features:
Information without integration. Contemporary life pours signal into the head continuously. 瑜伽師地論's diagnostic — mind filled with defiled impressions because 作意思惟 (deliberate thinking) is also 修 of the defiled sort — is sharp here. Most contemporary minds have plenty of 作意; almost all of it is in the wrong column of 起信論's analysis. 修行 re-trains which 作意 gets repeated.
Cultured knowing without practice. The "I've read about it" syndrome is named, anciently, as 言說住於放逸. The 修 pipeline that the canonical sources insist on is 聞法 → 持 → 如法修行 / 如說修行 — hear, retain, then practice in accordance. The skip-direct-to-feeling-good-about-it elides the middle of that pipeline.
Ordinary skill and extraordinary virtue bifurcated. Modern lives are highly skilled in domains, and quite unworked in the domain of breath, attention, restraint, and kindness. 瑜伽師地論's two-mode taxonomy — 防護受持修 (protecting body and precepts) and 作意思惟修 (working mind and wisdom) — is more relevant than ever, because most contemporary skills live in neither category: they are technique without 修 of self.
A useful contemporary parallel, with its limits clearly marked: contemporary psychology and neuroscience have shown, with some robustness, that habitual attention does rewire the brain — what they call neuroplasticity. The classical 熏習 mechanism is a deeper version of this observation: long-term inward conditioning changes what the mind tends to do spontaneously. But the classical framework insists on something the neuroscientific framing leaves out: the direction, the aim, and the endpoint are not neural; they are 斷界, 離欲界, 滅界 (sphere of cutting, sphere of dispassion, sphere of cessation). So when neuroscience says "you can rewire through repetition," it is describing the surface of 熏習; it is not yet describing the content, aim, or telos of修行.
A second contemporary parallel — useful up to a point and misleading past it — is the way LLMs are trained. 數習 (repeated exposure) is how patterns stabilize in training data. 數習 in修行 is also the mechanism by which the mind stabilizes. But the analogy fails fast: training optimizes a loss function, not 解脫; training produces outputs, not 涅槃; training has no 慈心; training has no capacity to 修遠離法. Don't mistake the surface similarity of "repetition changes stuff" for the depth. 起信論's 淨法 side has a telos: 修 the un-attached, until 不取不念 (not grasping, not mentally marking). That isn't pattern-matching; it's the inverse.
So what修行 offers, specifically, that contemporary culture is short on: 1. A way to interrupt the coupling of information consumption and self-image inflation (the 言說 vs 修行 cut). 2. A way to make daily, routine acts into 修身→修心→修慧 training rather than dead time. 3. A way to do this without depending on monastic structures, on charismatic teachers, or on belief in any particular metaphysics. 六祖's 若欲修行，在家亦得，不由在寺 still works. 4. A way to remain in difficulty without collapsing or hardening. 身、心、慧並修 (the cultivation of body-mind-wisdom in tandem) means when life fractures, the practitioner doesn't have to split. 5. A built-in permission to start small and today. 雜阿含's milk-squeezing moment makes修行 impossible to postpone.
Common Misreadings and Clarifications
Misreading #1: "修行 means going to temple or becoming a monk." Direct rebuttal in 壇經: 若欲修行，在家亦得，不由在寺 — you can cultivate as a householder; being-in-temple is not the issue. 古尊宿語錄's 着衣喫飯 being called 正大修行 is the same principle taken to daily life. The substance of practice is what you do where you are, with what you have.
Misreading #2: "修行 means meditation only." Half-correct. 增壹阿含's enumeration of 不殺生, 布施供養, 坐禪思惟, 聞法辨義, 不放逸, 斷漏 is interlocking, not hierarchical. 起信論's five gates (施, 戒, 忍, 進, 止觀) treat generosity and precept-keeping as equals to meditation. 俱舍論 distinguishes three 福業事 streams: 施, 戒, 修 — generosity is one, precepts is two, the meditation-quality is three. Meditation is one of three limbs, not the whole body.
Misreading #3: "修行 is about getting enlightened or having peak experiences." 溩山 responds directly. Even after 頓悟, the 習氣 of beginningless eons cannot be 頓淨; what 修 then means is 淨除現業流識 (moment-by-moment purification of currently-flowing karmic consciousness). Enlightenment is not the peak of a self-improvement curve but the reorientation under which 修 becomes possible as ongoing purification.
Misreading #4: "修行 is just becoming a good person." Too thin for 俱舍論's 等引善 — the term demands that the goodness be of the samādhi-bringing kind, that is, goodness which pervades and shapes mind-stream. Generic niceness doesn't train mind-stream; repetitive, attentive, inward practice does. The qualifier is the 等引 quality.
Misreading #5: "修行 is about calm and peace." Calm may be a by-product; the bracket of possible fruits in 瑜伽師地論 is 斷界, 離欲界, 滅界 — the sphere of cutting, of dispassion, of cessation. These are not relaxing states; they describe the ceasing of grasping. Practicing修行 while expecting relaxation is like training for surgery while expecting massage.
Misreading #6: "修行 is just for me, the individual self." The Mahāyāna corpus reframes immediately. 大方等大集經 ties 修 to 悲願 — the very reason to cultivate is the sight of sentient beings 受生老病死逼迫、被煩惱火燒、沈流惡道 (pressed by birth-old-age-sickness-death, burned by afflictive fire, sunk into unhappy migrations). 起信論's 淨法熏習 intrinsically works for all beings, since 真如法 tends toward the liberation of all. Selfish修行 is a half-formed 修行.
Misreading #7: "修行 and 戒 are opposed, or修行 is just for those past the stage of keeping precepts." 瑜伽師地論's typology already refutes this: 防護受持修 (protective cultivation: 修身 and 修戒) and 作意思惟修 (thoughtful cultivation: 修心 and 修慧). Keeping the precepts with attention is already 修 of one kind; sitting in contemplation is 修 of the other. Both are修行 — distinct in mode, identical in direction.
Misreading #8: "Once awakened, no further practice is needed." 溩山 offers the most concise refutation: 初心雖從緣得, 一念頓悟, 自理猶有, 無始曠劫習氣, 未淨, 淨除現業流識, 即是修也 — even after sudden awakening, the beginner-moment's still has unpurified 習氣; 修 continues until those are settled. 洞山 adds that 心不附物 is 真修行 — the very word 真 presumes 妄 (counterfeit), so the question of whether one is done arises precisely because one isn't.
Misreading #9: "修行 means a special state / something extra to ordinary life." 古尊宿語錄's 着衣喫飯 → 正大修行 refutes this. Chan, on this point, is most explicitly counter-intuitive: the very ordinariness of the next half-hour is where修行 lives. Not adding something to life; returning to it.
Misreading #10: "修行 is about doing nothing." The deepest layer, 〈勝慧菩薩問修行大法光明〉, is the place where doing-as-project is released into doing-as-no-grasping. But the same text does not say to skip the layers below; it says the highest practice is non-quantified, non-characterized, condition-free, and doing-free. Beginners who claim to have arrived at that layer are described in the text as "非諸愚夫有相有為所修行者少能行之" — not something the merely sign-seeking, conditioned, will-managed practitioner can perform. The texts do not let you skip from milk-squeezing minute one to "all doing ceases." They let you live the first.
Pulling the threads together: 修行 is a single Chinese word for an entire hierarchy of practice. Across sutras and śāstras, the word names a milk-squeezing moment, a lifelong accumulation, a systematic calm-and-insight tandem, a long mutual-conditioning in which pure tendencies gradually overpower the defiled, the bodhisattva's letting-go of every project, and the householder's just-eating-rice. What holds them together is one character — 修 — and what 修 means at its root is 等引善 (samādhi-bringing goodness that pervades the mind-stream) and 常行積集 (continuous practice and accumulation). Depth and duration, the two sides of the same work.
The texts are emphatic, across every period and tradition covered here, on three constraints: don't talk without practicing (大寶積經); don't think of the temple as the place (壇經); don't think of momentary clarity as the end (溩山). Within those constraints, the practice is ordinary, sustained, and available — even a finger-snap of 修習 慈心, even 着衣喫飯, even 淨除現業流識. The medieval Chinese Chan master who said 着衣喫飯 is 正大修行 was not being glib; he was honoring the canonical tradition's deepest insight — that修行 is what you do with this moment, repeatedly, attentively, with nothing extra required and nothing optional.
