聖行 (ārya-caryā, the holy practice) is a core term in the Buddhist path to liberation that is of paramount importance, yet all too easily "mythologized" or "conceptualized" by secular culture.
In a nutshell: 聖行 refers to the pure practices cultivated by noble ones (ārya) or bodhisattvas, aimed at eradicating all outflows (āsrava), transcending the three realms, and attaining outflow-free liberation and nirvāṇa.
In the contemporary context, when people speak of "holy" (聖), they often associate it with morally perfect personalities or transcendent, otherworldly states. But in the rigorous doctrinal framework of classical Buddhism, "holy" is neither a reputation nor an aura—it is a strict set of outflow-free (無漏, anāsrava, without defiling outflows) practices. It answers the most fundamental question of the path to liberation: When a person is no longer driven by afflictions and no longer held hostage by birth and death, how exactly do their actions, daily rhythms, attention, and mental states operate?
I. What This Concept Is Saying
To precisely locate "聖行" (ārya-caryā) within the entire path to liberation, we cannot rely on a single dictionary gloss. Rather, we must base ourselves on the scriptures, analyzing its complete architecture and boundaries through the progressive layers of the Āgamas, the Mahāvaipulya (Great Collected) sūtras, and the Nirvāṇa sūtras.
1. The Classical Boundary of "Holy": What Does "Far from All Outflows" Mean?
In the *Madhyama-āgama* (《中阿含經》), "holy" has a very concrete, substantive definition: one is far from all unwholesome and evil dharmas, from all outflows and defilements; one does not create the "seed of future existence" (當來有本, the fundamental cause of future birth-and-death); one does not engender the causes of feverish distress, painful retribution, birth, aging, illness, and death.
Every arising of thought in an ordinary person accumulates fuel for future saṃsāra (the "outflows" are the leaking and flowing of afflictions); the essence of "聖行" is precisely to sever this chain reaction of self-inflicted suffering.
2. Four Dimensions in the Scriptures: The Concrete Architecture of Holy Practice
Synthesizing the classical sūtras and śāstras, holy practice is not abstract philosophy but a pure discipline formed by the close interlocking of four major dimensions:
##### (1) Purity of Morality and Livelihood (Protection of Life's Conduct)
* Purity of livelihood (命行清淨): Body, speech, mind, and means of livelihood (life) are well-guarded and without deficiency; one does not exalt oneself or disparage others. * Guarding the sense faculties (守護諸根): When the six sense faculties meet external objects—eye seeing forms, ear hearing sounds, etc.—one achieves "not grasping at characteristics, not savoring them" (不受相、不味著). That is, one is not seduced by external details and features, does not crave the sweetness within them, and guards against greed and sorrow arising in the mind. * Clear awareness in coming and going (正知出入): In daily activities—bending and stretching, dressing and taking the bowl, walking, standing, sitting, lying down, speaking, remaining silent, and even sleeping—one maintains clear discernment (正知, samprajaña). * Guarding the precepts like guarding a life raft (護戒如護浮囊): The *Mahāparinirvāṇa-sūtra* (《大般涅槃經》) uses the simile of "a sea-crosser protecting his life-saving float" to illustrate the steadfastness with which a bodhisattva upholds the holy precepts. Even in the face of demonic obstacles or physical pain, one never gives rise to a defiled mind that craves the five desires; thus one abides in the "first immovable ground" (初不動地) and is not toppled by afflictions.
##### (2) Meditative Concentration and Contemplation of Impurity (The Restructuring of Holy Concentration and Wisdom)
* Dwelling alone in seclusion and eradicating the five hindrances (獨住遠離與斷五蓋): Far from noise and bustle, sitting cross-legged, one purges the five hindrances that veil the mind—sensual desire, ill will, sloth-and-torpor, restlessness-and-remorse, and doubt—and thereby accomplishes the fourth dhyāna. * Contemplation of impurity and contemplation of the skeleton (不淨觀與骨相觀): In the *Mahāparinirvāṇa-sūtra*, holy concentration and wisdom are concretized into an extremely profound contemplative practice: the bodhisattva observes his own body as nothing but impurity and filth, strips away skin and flesh, and focuses exclusively on contemplating the white bones (manifesting in blue, yellow, red, white, and other hues) to completely sever sensual desire; then he contemplates the linked bones (骨鎖), causing the body's bones to separate, thereby precisely cutting off the three desires (三欲): * Desire for appearance (形貌欲): Attachment to the body's outward form and contours. * Desire for demeanor (姿態欲): Attachment to movement, bearing, and manner. * Desire for subtle touch (細觸欲): Attachment to subtle tactile sensations such as skin contact and soft textures.
##### (3) Wisdom and the Attainment of the Outflow-Free Fruit (The Transcendence of the Three Realms)
* Seeing and knowing things as they are, and the exhaustion of the three outflows (如實知見與三漏盡): Within a pure and unwavering concentrated mind, one sees and knows the four noble truths (suffering, origin, cessation, path) and the outflows as they truly are, eradicating the outflow of desire (欲漏, kāma-āsrava), the outflow of existence (有漏, bhava-āsrava), and the outflow of ignorance (無明漏, avidyā-āsrava), achieving the outflow-free liberation of "birth is exhausted, the holy life is established, what had to be done has been done, and there is no further receiving of existence". * One's own domain and the four virtues (自境界與四德): The *Madhyama-āgama* compares this liberation to "a bhikṣu moving within his own domain, inherited from his father," endowed with four virtues: * Life (壽): Cultivating the four bases of psychic power (四如意足); * Form (色): Cultivating moral precepts and perfect deportment; * Bliss (樂): Accomplishing the fourth dhyāna; * Power (力): Possessing outflow-free liberation of mind and liberation by wisdom, able to subdue all demonic forces. * Non-action within action (不行於行): In the *Mahāvaipulya-mahāsaṃnipāta-sūtra* (《大方等大集經》), holy practice exhibits a high degree of dialectical transcendence. It does not adhere to eye-consciousness through mind-consciousness, nor to forms through dharmas; it has no grasping and no attachment (i.e., "no conditions," 無緣). The sūtra states that its essence is "all holy ones do not act within actions" (一切聖人不行於行), "neither aware nor unaware, nor greatly aware" (非覺非非覺亦非大覺); it can counteract all dharmas, yet does not dispute with any worldly dharma.
##### (4) Antidotes and Contentment with Few Desires (Four Illnesses and Four Medicines)
The *Mahāparinirvāṇa-sūtra* points out that those who have left home and cultivate the path are extremely susceptible to contracting the "four evil desires" (四惡欲, four illnesses); holy practice systematically counteracts them with the "four good medicines" (四良藥):
* Using the discarded-rags robe (糞掃衣, robes sewn from discarded fabric) to counteract the desire for clothing; * Using almsgiving/alms-food (乞食) to counteract the desire for food; * Using sitting beneath a tree (樹下坐) to counteract the desire for bedding and seats; * Using stillness of body and mind (身心寂靜) to counteract the desire for existence (有欲, craving for worldly existence, fame, and status).
3. The Original Scriptural Framework: The System of Five Practices and the Simile Structure
In the Mahāyāna *Mahāparinirvāṇa-sūtra*, holy practice does not exist in isolation; it is one of the "five practices" (五種之行) that a great bodhisattva (bodhisattva-mahāsattva) should cultivate: 1. Holy practice (聖行): Diligently cultivating the outflow-free path through morality, concentration, and wisdom, eradicating afflictions, and entering the stream of the noble ones (the foundation of self-cultivation). 2. Brahma practice (梵行): With a pure mind, practicing loving-kindness, compassion, sympathetic joy, and equanimity, removing suffering and bestowing happiness (the practice of transforming others). 3. Heavenly practice (天行): The wondrous practice arising in accord with the foremost truth (the middle way, ultimate truth, the nature of thusness). 4. Infant practice (嬰兒行): With great compassion, the bodhisattva manifests in accord with the small goodness of humans, gods, and the two vehicles (like holding up a yellow leaf to stop a child's crying, or a hollow fist to deceive a child), skillfully guiding beings. 5. Sick practice (病行): With compassion rooted in sameness (同體大悲), the bodhisattva manifests in accord with beings' afflictions and suffering (like Vimalakīrti manifesting illness), sharing in suffering to liberate beings.
In this system, holy practice is the cornerstone of the entire edifice of bodhisattva conduct—only by first eradicating one's own outflows and distancing oneself from defilement through holy practice can one then, without a defiled mind, descend to transform sentient beings.
II. Walking Through It in Daily Life
To keep holy practice from becoming a mere antiquarian term on paper, let us place ourselves in the most familiar scenarios of contemporary life—"scrolling through one's phone late at night" and "workplace socializing, evaluations, and anxiety"—and strictly compare against the classical definitions to see how holy practice lands in the micro-level of perception.
Scenario One: Late-Night Short Videos/Social Media Scrolling
* The ordinary person's automatic reaction (defiled flowing): In the dead of night, you swipe the screen. Seeing an attractive person, you generate admiration for "appearance"; seeing fashionable outfits and refined lifestyles, you generate envy for "demeanor"; seeing an ad for a plush, soft-feeling sofa or mattress, you generate craving for "subtle touch." *The eye sees the image (eye-consciousness meeting form), and the mind immediately adheres (grasping at characteristics, savoring).* Then the algorithm keeps pushing content, and the mind generates greed and the anxiety of wanting but not getting. The next morning you wake up exhausted in body and mind. This is a textbook case of "the leaking of outflows," creating the afflictive causes of "the seed of future existence" without awareness.
* The micro-level walkthrough of "holy practice" and its classical mapping: 1. Guarding the sense faculties and clear awareness: As your finger scrolls, the six faculties meet their objects. Holy practice requires "not grasping at characteristics, not savoring". When an attractive image appears on the screen, you can clearly know "eye-consciousness is operating, form is appearing," but you do not treat the image as an extension of your real self, and you do not enter into the savoring of its sweetness. 2. Counteracting the three desires (appearance, demeanor, subtle touch): Seeing a "perfect" image packaged with editing and filters, the mind can apply the insight of "holy concentration and wisdom": this is nothing but skin and flesh wrapping bones, a fabricated combination of pixels and light. Precisely demolish the delusions of "desire for appearance, desire for demeanor, desire for subtle touch". 3. Do not dwell on the past, nor long for the future: The wisdom of the *Bhadra-kārā* verse (《跋地羅帝偈》) from the Āgamas manifests here—do not savor the stimulation just scrolled past (not dwelling on the past), do not anticipate that the next video will be even more exciting (not longing for the future); stop the finger in the present moment, feel the body's fatigue, and abide in the breath. 4. The four medicines as antidotes: With this stillness of body and mind, counteract the craving for a sense of existence in the virtual world (using stillness to treat the "desire for existence").
Scenario Two: Workplace Socializing, Evaluations, and Anxiety
* Where most people make their biggest mapping error: Many people think that "holy conduct" in the workplace means being a "nice person," swallowing one's anger, or preaching lofty moral platitudes from on high. This is a serious mapping error. Holy practice is not cowardice, nor is it moral coercion; it is "purity of livelihood" and "non-action within action".
* The micro-level walkthrough of "holy practice": 1. Purity of livelihood: In making a living (life) in the workplace, adhere to your bottom line; do not gain benefits through fraud, flattery, or harming others. In a team, "do not exalt yourself, do not disparage others" (不自舉，不下他)—do not exaggerate your own contributions, and do not denigrate your colleagues' efforts. 2. Staying far from impure gains: Facing gray-area income or the temptation of benefits that violate your principles—just as King Bimbisāra vowed, "cultivating the holy practice, I will never accept impure things" (修聖行終不受取不淨之物)—the mind remains as solid as the sea-crosser's float, never opening a leak. 3. Non-action within action, not disputing with dharmas: When facing workplace competition for evaluations, disputes over fame and profit, one can outwardly complete one's work reasonably and properly, but inwardly one does not cling to "mind-consciousness and dharmas". See clearly that praise and slander are both impermanent fluctuations; the mind is not moved by forms, sounds, smells, or tastes (abiding in the first immovable ground). Even while solving problems within the situation, inwardly one "does not dispute with any dharma", displaying an extremely clear, emotionally un-hijacked stability.
III. Why Contemporary People Need It
Contemporary society is saturated with information overload, consumerism, and utilitarian anxiety. Modern people seemingly possess the richest material wealth and entertainment in history, yet their minds are in an unprecedented state of "high leakage."
1. A Contemporary Contrast: Algorithmic Life and the "Outflows"
The underlying logic of modern technology (recommendation algorithms, social media, short videos) is precisely the precise capture of the human tendency to "grasp at characteristics and savor" (受相與味著). Algorithms analyze your desires and endlessly push content that triggers your "desire for appearance, desire for demeanor, desire for subtle touch". In neuroscience, this is called the "dopamine prediction error mechanism"—each swipe is a stimulus, and the brain becomes conditioned in its relentless pursuit of reward, resulting in fragmented attention and psychological addiction.
The concept of "outflows" (諸漏) proposed by Buddhism thousands of years ago precisely describes this state: your attention and energy are constantly leaking outward and being depleted through the eyes, ears, nose, tongue, body, and mind. What contemporary people need—"holy practice"—is a firewall for the mind. It teaches us how to implement "restraint of the faculties" (根律儀, guarding the sense faculties) within the encirclement of algorithms and reclaim sovereignty over our attention.
2. A Contemporary Contrast: AI and "Seeing, Hearing, Awareness, and Knowing" of Consciousness
With the development of artificial intelligence (AI), machines can generate perfect images, write heartfelt texts, and even simulate human decision-making and thinking. This compels contemporary people to confront an ultimate question: If information processing, logical reasoning, and even artistic creation can all be replaced by algorithms, where exactly does the uniqueness of the human mind lie?
The *Mahāvaipulya-mahāsaṃnipāta-sūtra*'s description of holy practice displays a startling prescience here: holy practice is "not all characteristics, not all feelings, not the seeing, hearing, awareness, and knowing of the mind, thought, and consciousness" (非一切相、非一切受，非諸心意識之見聞覺知). What AI processes is precisely "the seeing, hearing, awareness, and knowing of mind and consciousness" and "forms through dharmas". If we equate the mind with data input and logical output, we remain forever trapped in the "actions of the three realms" that machines can also simulate. Holy practice points to a kind of outflow-free awareness that transcends attachment to mind and consciousness—not stuck to characteristics, not dragged by feelings. This provides contemporary people with an ultimate coordinate for anchoring the reality of the mind when facing the wave of technology.
3. The Limitations of Analogy and Unresolved Questions
Although neuroscience research on neuroplasticity has demonstrated that meditation can change cortical thickness, and cognitive psychology has confirmed that "clear awareness and right mindfulness" (正知正念) can reduce anxiety, it must be clearly stated: scientific research and the holy practice of Buddhism have an essential boundary difference. Scientific research remains at the level of "third-person objective observation" and "optimization of mundane mental functions" (such as improving work efficiency or reducing stress); the ultimate goal of "holy practice" is the eradication of the outflow of desire, the outflow of existence, and the outflow of ignorance, the complete liberation from birth-and-death saṃsāra, and the realization of great nirvāṇa. Science currently can neither verify "the three realms of saṃsāra" and "the attainment of the outflow-free fruit," nor can it use instruments to measure the nirvāṇa state of "permanence, bliss, self, and purity" (常樂我淨). Therefore, we can use contemporary scientific material as an aid to understanding the mechanisms of mental training, but we must never equate scientific research with the outflow-free liberation of holy practice.
IV. Common Misreadings and Clarifications
In modern people's attempts to understand "holy practice," several fatal points of confusion easily arise, which must be clarified one by one according to the classical sūtras and śāstras:
Misreading One: Equating "Holy Practice" with Secular Moral Nobility (Narrowing "Holy" to a Moral Paragon)
* Clarification: Secular morality is usually built on the foundation of "the opposition of good and evil" and "the self"—"I" am a noble person, "I" am doing good deeds. The classical criteria clearly state that the core of holy practice is "no thoughts, no conditions" (無想無緣) and "not acting within the actions of the three realms" (不行三界之行). If one observes precepts or does good deeds with self-praise (自舉), disparagement of others (下他), or for the sake of fame and profit, then one has completely fallen into "impure gain" and worldly defilement. Holy practice transcends mere secular morality; it requires that while observing precepts and doing good, the mind does not adhere to characteristics and has no grasping or attachment.
Misreading Two: Treating "Holy Practice" as the Exclusive Province of Monastics, Believing Modern People Cannot Cultivate It
* Clarification: Although the *Mahāparinirvāṇa-sūtra* mentions items such as leaving home, observing precepts, and the four medicines, the *Madhyama-āgama* and the *Mahāsaṃnipāta-sūtra* clearly show that the core of holy practice lies in the operating mode of the mind—"do not dwell on the past, nor long for the future," "wisdom and awareness of dharmas in the present moment", and "guarding the sense faculties, clear awareness in coming and going". Whether one is on a carpet, in an office, or in the mountains, as long as at the very moment the six faculties meet their objects you achieve not grasping at characteristics and not savoring, cutting off the leakage of afflictions, you are practicing holy practice.
Misreading Three: Confusing "Holy Practice" with the Bodhisattva's "Sick Practice" and "Infant Practice"
* Clarification: In the "five practices" (五行) system of the *Mahāparinirvāṇa-sūtra*, the five are clearly stratified and must not be confused: * Holy practice is the cornerstone—the "self-benefiting outflow-free practice" of cutting off afflictions and diligently cultivating morality, concentration, and wisdom. * Infant practice and sick practice are "compassionate skillful means" (慈悲化用) that bodhisattvas who have already attained the outflow-free wisdom of the higher grounds employ to rescue sentient beings (manifesting in accord with minor goodness, manifesting in accord with illness and affliction). If an ordinary person, without having first eradicated their own defilements and three desires through "holy practice", rashly imitates the bodhisattva in "manifesting in accord with affliction" (such as indulging one's desires or temper while calling it "cultivating sick practice, going with the flow to save beings"), this is what is called "sinking oneself before rescuing the drowning"—a complete inversion of the order of cultivation.
Misreading Four: Misinterpreting the Contemplation of Impurity and the Skeleton Contemplation as "World-Weary Depression"
* Clarification: The contemplation of impurity and skeleton contemplation in the *Mahāparinirvāṇa-sūtra* (counteracting the three desires of appearance, demeanor, and subtle touch) is by no means intended to produce psychological disorders or world-weariness. It is a precise "mental scalpel". Its function is to break through the human being's excessive attachment to and pathological craving for the illusory beauty of the physical body (form). By seeing clearly the physical nature of the body, the practitioner is liberated from intense craving-anxiety and attains genuine peace ("the immovable mind," 得不動心) and fearlessness. This is a detoxification process that uses cool wisdom to counteract feverish affliction, not depression or withdrawal.
Conclusion
"聖行" is by no means a religious dogma suspended in the clouds; it is an extremely rigorous, profound, and penetrating engineering project for the liberation of the mind. From the present-moment right mindfulness of "not dwelling on the past, not longing for the future" in the Āgamas, to the dialectical transcendence of "non-action within action, not disputing with dharmas" in the *Mahāsaṃnipāta-sūtra*, to the steadfast practice of "guarding the precepts like guarding a life float, the four medicines counteracting the four illnesses" in the *Nirvāṇa-sūtra*, it points us to a path:
In the complexity of mundane life, we can completely rein in the leaking six faculties, see through delusive craving, and remain unshaken by afflictions. Outwardly, respond to all matters reasonably and properly; inwardly, abide in stillness and immovability within reality—this is the contemporary power of holy practice.
