What this concept is saying
真常 (zhēncháng, “true constancy” or “the truly enduring”) names the ever-present reality that becomes evident when attachment to both “ordinary” and “holy” has exhausted itself and delusive conditioning is released. It is neither annihilation nor a frozen, deathlike permanence.
That definition is easy to repeat and unusually easy to misunderstand. The word “constant” tempts us to imagine an indestructible spiritual object hidden somewhere inside us: a metaphysical core that survives while everything else changes. Chan teachings block precisely that move. True constancy is not another thing for the mind to locate, possess, or defend. It is spoken of as 體露真常 (tǐ lù zhēncháng, “true constancy stands completely revealed”): not something newly manufactured, but what is evident when the activity that conceals it is no longer being sustained.
A verse preserved in the *Records of the Ancient Worthies* (*Guzunsu Yulu*) expresses the structure closely:
“The numinous light shines alone, far beyond sense faculties and their objects; true constancy stands revealed, unrestricted by words and letters. Mind-nature is unstained, originally complete; only leave delusive conditions, and there is the thus-thus Buddha.”
The original terms matter. “Beyond faculties and objects” does not mean blindness to sights and sounds. 根塵 (gēn-chén) refers to the paired structure of sense faculty and sense object: eye and form, ear and sound, mind and mental objects. True constancy is not confined to anything found on either side of that encounter. Nor does “unrestricted by words” mean that language is useless. The verse itself uses language. It means that no definition, however accurate, can turn living realization into a verbal possession.
Three movements in the classical accounts deserve careful attention.
First, 凡聖情盡 (fán-shèng qíng jìn): “the affective attachment to ordinary and holy is exhausted.” Here 情 is more than emotion. It is the invested, appropriating tendency by which we establish identities and oppositions: “I am an ordinary person”; “that person is spiritually advanced”; “I must escape this impure condition and acquire a sacred one.” The teaching does not say that wisdom and delusion are indistinguishable in their consequences. It says that craving for the identity of “sage” and aversion toward the identity of “ordinary being” perpetuate the very subject-object structure one hopes to transcend.
The *Records of the Ancient Worthies* makes this explicit:
“There is no need to love the holy: ‘holy’ is an empty name. There is no need to despise the ordinary: ‘ordinary’ is falsely established. When attachment to holy and ordinary is exhausted, this is called ‘true constancy standing revealed.’”
Thus “exhausted” does not mean violently suppressing admiration, shame, aspiration, or moral discernment. Suppression would still be an emotional strategy undertaken by someone trying to become someone else. What ends is the taking-up of “ordinary” and “holy” as fixed identities.
Second, 但離妄緣 (dàn lí wàngyuán): “only depart from delusive conditions.” A 妄緣 (wàngyuán) is not merely an unpleasant circumstance or an external distraction. It is the conditioned involvement through which mind follows appearances, imputes fixed reality to them, and constructs grasping, resistance, and selfhood around them. A ringing phone is not in itself a delusive condition. Seeing the notification, imagining what it may mean about one’s status, feeling compelled to check it, and silently building a self around the response—that is the machinery of delusive conditioning in operation.
“Leaving” such conditions therefore does not necessarily mean leaving one’s job, family, city, or devices. It means ceasing to lend delusion the participation by which it continues. This is why the verse says that mind-nature is “originally complete.” One does not polish delusion until it becomes true constancy. One sees through and relinquishes the appropriating activity that obscures what does not depend on that activity.
Third, 事理不二 (shì-lǐ bù’èr): “phenomena and principle are not two.” The *Recorded Sayings of Yangshan Huiji* preserves Guishan’s verse:
“When attachment to ordinary and holy is exhausted, true constancy stands revealed. Phenomena and principle are not two: this is precisely the thus-thus Buddha.”
Here 事 (shì) means concrete events and differentiated phenomena; 理 (lǐ) means the truth or principle disclosed through them. True constancy is therefore not a transcendent background from which changing life must be excluded. Washing a cup, hearing criticism, caring for a sick child, and watching the body age remain changing events. Realization does not make them motionless. It reveals that the truth is not somewhere else, sealed off from their arising and passing.
This is the force of sayings such as “a thousand changes and ten thousand transformations do not go outside true constancy,” preserved in the *Jingde Record of the Transmission of the Lamp*. Change does not damage true constancy, because true constancy is not one more changeable object. But neither should the saying be converted into the theory that a single cosmic substance disguises itself as everything. The records repeatedly refuse to let “true constancy” settle into a thing that can be measured through being and nonbeing, arising and extinction.
This also explains why Chan distinguishes it from both impermanence wrongly understood as sheer erasure and 死常 (sǐcháng, “dead constancy”). Dead constancy is permanence imagined as immobility: a sterile absolute untouched by relationship, conduct, compassion, or change. True constancy is not threatened by “the hundred rivers flowing.” The *Jingde Record* places “true constancy unstained by dust” beside the teaching that “on the ground of ultimate reality, not one speck of dust is admitted; within the gate of Buddhist activity, not one dharma is abandoned.” Nothing can stain the ultimate, yet nothing in the field of practice may be neglected.
That pairing locates true constancy within the path of liberation. At the level of realization, nothing needs to be added to mind-nature. At the level of conduct, habits, injuries, responsibilities, and compassionate activity are not thereby cancelled. Sudden recognition and the gradual clarification of conditioning are not enemies. One may awaken to what was never defiled while still having deeply learned reactions that require honest practice.
Yangshan consequently tells practitioners to “recognize mind and reach the root.” Supernormal powers—the traditional 三明六通 (sānmíng liùtōng, three knowledges and six superknowledges)—are “matters at the outer edge of holiness,” not true constancy itself. Extraordinary experiences may arise and pass; fascination with them simply rebuilds the seeker who hopes to become special.
Most importantly, true constancy is not fulfilled as private inward peace. The *Records of the Ancient Worthies* warns:
“Though one alone accords with true constancy, if the compassionate heart is not yet vast, one has not gone far enough.”
If realization makes a person indifferent to suffering, it has either been misunderstood or has not penetrated conduct. Because phenomena and principle are not two, compassion is not an optional social application added after private enlightenment. The colleague, stranger, child, animal, and adversary all appear within the very field in which truth is realized.
A walkthrough in everyday life
Imagine an ordinary evening commute. You are tired after working late. While standing on a crowded train, you open your phone and see that a message you sent to someone close to you has been read but not answered.
The visible screen, bodily fatigue, train noise, other passengers, and the message are changing phenomena. True constancy does not ask you to deny them, label them unreal, or retreat into a blank inner refuge.
Then recognition begins constructing a story: “They are ignoring me.” Memory supplies earlier disappointments. The body tightens. The mind rehearses a reply. None of these passing events is a moral failure. The delusive turn occurs when the interpretation is silently treated as the complete reality and appropriated into “what this means about me.” A moment of uncertainty becomes an abandoned self confronting an inconsiderate other.
Now the opposition between “ordinary” and “holy” may appear in contemporary clothing. One thought says, “I am too needy and reactive.” Another says, “If I were truly mindful, none of this would disturb me.” The first fixes an ordinary, defective identity; the second imagines a holy identity that must remain untroubled. Aversion to the first and desire for the second are precisely the 凡聖情 whose exhaustion the classical verse describes.
The common mistake here is to map “leaving delusive conditions” onto suppressing the hurt. One tries to become blank, repeats “everything is empty,” or refuses to send any message lest action betray attachment. But emotional numbness is not true constancy. It may be another conditioned strategy—an idealized spiritual self protecting itself from vulnerability.
A more faithful inspection proceeds differently.
You notice the pressure in the chest as pressure, not as proof of abandonment. You recognize the sentence “They do not care about me” as an interpretation, not as direct perception. You see the wish to retaliate and the wish to appear serenely enlightened. Neither is made into “me” or “my true nature.” This is a small, practical instance of withdrawing participation from delusive conditioning.
Nothing special has to replace the story. The train continues moving. Hurt may remain. The message remains unanswered. Yet for a moment, experience is no longer organized around defending an ordinary self or acquiring a holy one. This is not yet a warrant to announce realization, but it illustrates what “revealed rather than produced” means: clarity appears through nonappropriation, not through constructing a superior state.
Then 事理不二 becomes ethically decisive. You still have to act within the situation. Perhaps you wait until the body settles and ask, “I noticed I became anxious when I didn’t hear back. Are you all right?” Perhaps you discover that the other person was caring for a parent or simply needed space. Perhaps there is a genuine pattern of neglect that requires a boundary. True constancy does not dictate one uniform response. It allows a response less distorted by the demand to secure a self.
The same walkthrough applies while parenting. A child has a public meltdown. Sensations and sounds arise; embarrassment follows; the thought “Everyone thinks I am a bad parent” appears. Then an imagined “good parent” is loved and the present “failed parent” is hated. Leaving delusive conditions does not mean abandoning the crying child or pretending embarrassment is absent. It means seeing the identity-making process clearly enough that attention can return to the child’s actual need. The “gate of Buddhist activity” abandons no dharma: regulation, safety, patience, apology, and limits all still matter.
It also applies to algorithmic life. A recommendation system learns what prolongs attention; it can repeatedly present material that activates fear, desire, outrage, or self-comparison. But the algorithm is not identical with Buddhist 妄緣. The analogy has limits: a technical system can shape exposure, while delusive appropriation concerns the lived structure of grasping and mistaken identification. Nor does neuroscience settle the Buddhist account of mind-nature. Scientific models can investigate attention, habit, affect, and self-representation, but the interpretation of consciousness and the scope of first-person realization remain contested. These comparisons may illuminate conditioning; they do not amount to scientific proof of true constancy.
In practice, while scrolling, one might notice this sequence: an image appears; comparison arises; the identity “I am behind” forms; an idealized person is projected; desire and resentment reinforce both poles. “Ordinary and holy” have become “unsuccessful me and perfected online other.” To see the sequence without feeding it is already to loosen the delusive condition. To put down the phone may be wise, but the decisive point is not the physical gesture alone. One can put down the phone while continuing the comparison for hours.
Why contemporary people need it
Contemporary life trains us to understand improvement almost entirely as acquisition: more information, more visibility, more optimization, better metrics, a stronger personal brand, even a more impressive spirituality. True constancy introduces a radically different possibility: the deepest freedom is not acquired as an enhancement of the self-project. It becomes evident as the compulsive construction of that project is relinquished.
This does not make learning, therapy, education, social reform, or disciplined practice unnecessary. Those operate within the field of conditions and may be indispensable. True constancy addresses a different question: even after circumstances improve, what prevents the mind from turning every improvement into a new identity to defend? Without attention to that root, success changes the content of grasping but not its structure.
The teaching is especially valuable amid instability. If security means preserving a particular role, body, relationship, belief, or emotional state, change will always appear as an existential threat. True constancy does not promise that these things will remain. It discloses a freedom that is not constituted by holding them still. Hence it is neither denial of impermanence nor surrender to nihilism.
It also corrects a common spirituality of self-rejection. Many people approach practice because they cannot tolerate who they presently are. They imagine awakening as promotion from the category “ordinary” into the category “holy.” Chan’s language is almost mischievously direct: attachment to both categories must end. One cannot reach freedom by making the prison’s preferred cell more beautiful.
At the same time, the warning about compassion prevents this teaching from becoming refined escapism. “I rest in the unchanging while the world suffers” would divide principle from phenomena. If true constancy is genuinely disclosed, it should weaken self-protection and make compassionate responsiveness more available. One no longer needs another person to confirm one’s identity before taking their suffering seriously.
This is also why the Chan records subject the phrase itself to suspicion. Huanglong Huinan calls the inherited saying about true constancy “the ancients’ leftover broth and spoiled rice.” He is not dismissing its truth. He is confronting practitioners who consume the vocabulary secondhand and mistake familiarity for realization. Another master worries that producing “words about true constancy” may allow a subtle verbal attachment to flow on in the dark.
The lesson is pointed: “true constancy” can become the final and most sophisticated delusive condition. The mind may abandon crude possessions only to possess an absolute.
Common misunderstandings and clarifications
1. “True constancy is an eternal soul hidden inside the person.”
The classical material does not authorize that simplification. It does speak positively of mind-nature, numinous light, true self, and true purity, particularly in language associated with the ultimate teaching of nirvāṇa. But Chan simultaneously denies that true constancy is an independently graspable entity outside present experience. It is disclosed when subject-object appropriation and attachment to ordinary and holy are exhausted. Turning it into “the real thing inside me” immediately restores the owner and the owned.
2. “Because it is constant, it never changes and therefore resembles an inert substance.”
That is 死常, dead constancy. The records instead ask how “the hundred rivers flow” if true constancy is unstained, and answer through the inseparability of ultimate truth and unrestricted activity. “A thousand changes and ten thousand transformations do not go outside true constancy” does not freeze change; it prevents us from imagining truth as a competing object located elsewhere.
3. “True constancy contradicts impermanence.”
It contradicts neither the arising and passing of conditioned phenomena nor the practical truth of aging, loss, and death. It rejects the inference that because conditioned things pass away, reality must reduce to sheer annihilation. Conversely, it rejects the attempt to rescue meaning by positing a rigid permanent thing. A verse in the *Jingde Record of the Transmission of the Lamp* describes the point as “free and at ease, neither annihilation nor [dead] permanence.” The teaching is deliberately positioned beyond those two views.
4. “Leaving delusive conditions means avoiding worldly conditions.”
A monastery can become a field of ambition, comparison, and self-construction; a crowded kitchen can become a field of clear and compassionate practice. External simplification may support practice, but 妄緣 is not synonymous with society, work, technology, sexuality, or family life. The key issue is how appearances are followed, solidified, and appropriated.
5. “Exhausting attachment to ordinary and holy erases ethical distinctions.”
It erases neither consequences nor discernment. Cruelty and compassion do not become interchangeable. What ends is identity-bound attachment: despising “the ordinary” and craving “the holy.” The formula “ultimate reality admits not one speck of dust; the gate of myriad practices abandons not one dharma” is the safeguard. Nothing can stain the ultimate, yet conduct still matters completely within lived relations.
6. “A blank or dissociated state is true constancy.”
Numbness, spacing out, reduced affect, and temporary cessation of thought are conditioned experiences. They arise and pass and may have psychological or physiological causes. True constancy is not defined by the absence of thought or feeling. Chan speaks of luminosity and responsive functioning as well as stillness; it tests realization amid raising and lowering a staff, speaking and silence, engagement and release.
7. “An extraordinary meditation experience or psychic power proves realization.”
Yangshan expressly ranks the three knowledges and six superknowledges as peripheral matters of holiness. Any unusual experience can become material for a newly exalted self. The decisive matter is “recognizing mind and reaching the root,” expressed in freedom from ordinary-holy appropriation and in undivided compassionate activity.
8. “If mind-nature is originally unstained, practice is unnecessary.”
Original nondefilement does not mean that greed, fear, aggression, and habitual confusion have no effects. True constancy is not manufactured by practice, but delusive conditioning must cease being continually reenacted. The records therefore unite radical disclosure with “not abandoning a single dharma” in the many gates of practice. Ethical discipline, meditation, wisdom, repentance, and compassion do not create the real; they clarify the conditions under which it is no longer concealed.
9. “Understanding this explanation means understanding true constancy.”
This is the misunderstanding the Chan masters target most sharply. Yangshan tells his listeners to turn the light around and reflect for themselves, not merely memorize his words. Huanglong asks whether practitioners can actually examine the inherited saying. The phrase is a direction, not a possession.
True constancy finally occupies a precise place on the path of liberation. It prevents insight into impermanence and emptiness from collapsing into nihilism; prevents affirmative language about Buddha-nature from hardening into eternalism; prevents sudden awakening from excusing unfinished habits; prevents disciplined practice from becoming self-manufacture; and prevents private realization from separating itself from compassion.
Its question is not, “What permanent thing can I secure?” It is: when the one trying to secure an ordinary or holy identity no longer feeds that division, what is already evident—and how does that realization live as wisdom and compassion in the midst of the hundred rivers flowing?”
