Hello. I am glad to explore with you the concept of "nitya-sukha-ātman-śubha" (常樂我淨), a core concept brimming with the ultimate wisdom of Mahāyāna Buddhism.
If you have any familiarity with Buddhism, you have likely heard the eight characters "impermanence, suffering, no-self, impurity" (無常、苦、無我、不淨). In many people's impression, Buddhism always seems to carry a cool, even somewhat pessimistic undertone, teaching us to let go of everything, see through the mundane world, and move toward an "emptiness" in which nothing exists.
But is that really so? Is the endpoint of the path of liberation merely a dead, silent nothingness?
The Mahāyāna *Mahāparinirvāṇa-sūtra* (《大般涅槃經》) offers a completely different answer. At the summit of the path of liberation, what awaits the practitioner is not a cold void, but four absolute qualities that are extremely abundant, complete, and real — 「常、樂、我、淨」 (nitya-sukha-ātman-śubha, "permanence, bliss, self, purity").
Today, let us completely dissect this concept, see where it sits on the map of the entire path of liberation, and how it can offer an antidote to the spiritual predicaments of contemporary people.
What This Concept Is Saying
To understand 常樂我淨 (nitya-sukha-ātman-śubha), we must first know its coordinates on the map of Buddhist cultivation and study.
Sentient beings revolve through birth and death (in the classics, this is often called the "twenty-five modes of existence" (二十五有, pañcaviṃśati-bhava), i.e., the twenty-five states of being within the three realms), taking the body-mind and external environments that are pieced together by causes and conditions and arise-and-perish in an instant, as permanent, blissful, autonomous, and pure. In Buddhism this is called the "four perversions" (四顛倒, viparyāsa) of ordinary beings. To break this clinging, the Buddha proclaimed in the early teachings "impermanence, suffering, no-self, impurity" (無常、苦、無我、不淨) — this is like using a potent medicine to cure sentient beings' disease of craving.
However, if practitioners (such as the two vehicles of voice-hearers (聲聞, śrāvaka) and solitary-realizers (緣覺, pratyekabuddha)) go this far and take "impermanence, no-self" as the absolute, final reality, thinking that nirvāṇa is complete annihilation into ashes, they fall into another kind of inversion. The *Mahāparinirvāṇa-sūtra* points out that, in order to free sentient beings from these two kinds of inversion, the Tathāgata revealed the ultimate truth (第一義諦, paramārtha-satya) — the 常、樂、我、淨 that the Tathāgata and Mahāparinirvāṇa truly possess.
It is composed of four extremely rigorous dimensions, and absolutely cannot be understood reductively through worldly concepts:
1. 常 (nitya, absolute permanence): Worldly permanence is "living a bit longer"; the "permanence" of nirvāṇa refers to the essence of the Tathāgata and nirvāṇa being permanent and unchanging, not originally absent and only now present. It is not assembled from conditions, and therefore cannot be destroyed when conditions disperse. Whether or not a Buddha appears in the world, this true nature is there all along — it is only that sentient beings are covered by afflictions and cannot see it. In the early *Dīrghāgama-sūtra* (《長阿含經》), this "permanence" was depicted through worldly projection as the wheel-turning sage king's (轉輪聖王, cakravartin) "long life without premature death" and the soft-reed grass of the natural world that "stays green in winter and summer alike." 2. 樂 (sukha, great bliss transcending suffering and pleasure): Worldly bliss is the pleasure when desires are satisfied; in essence it is the "suffering of change" (壞苦, vipariṇāma-duḥkha, the pain when pleasure fades). The "bliss" of nirvāṇa, by contrast, is called "the great bliss of neither suffering nor pleasure" or "the supreme, wondrous, quiescent bliss." It no longer depends on any external stimulus and undergoes no change whatsoever. Just as the *Dīrghāgama-sūtra* describes the wheel-turning sage king's realm where "the people of the land are peaceful and happy, free from affliction," it is an absolute tranquility without lack and without fear. 3. 我 (ātman, absolute sovereignty and mastery): The worldly "self" is a delusion built upon the "five aggregates" (五陰, pañcaskandha: form, feeling, perception, volition, consciousness). In buddha-nature there is no such false, arising-and-perishing self. But because the Tathāgata has realized permanence and unchangingness, and attained great sovereignty, unswayed by any external state or affliction, and because the Tathāgata's body is "not produced by causes and conditions," it is therefore called true "having a self." 4. 淨 (śubha, supreme purity): The "purity" of nirvāṇa is not the cleanliness of having taken a bath, but includes four kinds of "great purity": the eternal severance of the twenty-five modes of existence (completely cutting off the defilement of birth and death in the three realms), purity of karma, purity of body (the Tathāgata's dharma-body is permanent), and purity of mind (the Buddha-mind is absolutely free of outflows and afflictions). The *Dīrghāgama-sūtra* uses the imagery of the wheel-turning king's realm "without thorns or pits," "without mosquitoes, gadflies, or poisonous insects," and "like oil spread on the ground, clean and lustrous" to concretize this perfect state without any impurity.
Classical metaphor: Losing the jewel in the spring pond To illustrate this principle, the *Mahāparinirvāṇa-sūtra* left behind an extremely subtle metaphor that must be matched point by point. The Buddha said: just as someone drops a precious vaidūrya jewel into a deep pond in spring, the crowd jumps into the murky water and frantically fishes out tiles, stones, grass, and wood from the bottom, joyfully shouting "I found the jewel!" (This symbolizes ordinary beings taking the illusions of the world as nitya-sukha-ātman-śubha, or two-vehicle practitioners taking "impermanence, suffering, no-self, impurity" as the final absolute truth). Only the true wise one, employing skillful means, waits for the water to clear, and finally, in the clear water, sees and retrieves the true vaidūrya jewel (This symbolizes Mahāyāna bodhisattvas and the Tathāgata, after cleansing away afflictions, directly realizing the true 常、樂、我、淨 within buddha-nature).
A Walkthrough in Everyday Life
Now, let us use concrete scenarios from contemporary life to make a rigorous mapping and walkthrough of worldly deluded attachments versus the true "nitya-sukha-ātman-śubha." Let us see how we are fishing for stones in murky water.
1. Intimate relationships and the misalignment of "nitya" * Everyday scenario: You are in an extremely compatible intimate relationship, and you tell your partner, "Let us love each other like this forever." When the other person's feelings change with time and pressure (causes and conditions), you feel unbearably pained. * Walkthrough exposure: You have taken a "relationship" (a dharma produced by causes and conditions) patched together from hormones, projections of the family of origin, and the current state of life, as the unborn and undying "nitya." The true "nitya" absolutely does not depend on the maintenance of external conditions. Anything that requires "deliberate cultivation" is necessarily impermanent. * The nitya of nirvāṇa: It is the essence of awareness within you that can perceive joy and sorrow yet is neither born nor destroyed, independent of anyone's love or lack of love.
2. Scrolling phones, chasing dopamine, and the misalignment of "sukha" * Everyday scenario: After work, you collapse on the sofa scrolling through short videos, playing games, or decompressing through frantic shopping. After scrolling, what greets you is deeper emptiness and exhaustion. * Walkthrough exposure: What you are pursuing is the "feeling-pleasure" of sensory stimulation. According to the Buddhist definition of the five aggregates, the "feeling aggregate" (受陰, vedanā-skandha) is the sheer reception and perception of sensations. This kind of pleasure is built upon the alleviation of suffering (craving stimulation because of boredom and exhaustion). Once the stimulation threshold rises, the pleasure turns into pain. * The sukha of nirvāṇa: It is "great bliss." Like when you have completely finished a massive project and resigned from all the troublesome positions — the extreme relaxation and quiescence of no longer needing to "chase" anything. No phone needed, no material goods needed; it is complete in itself.
3. Workplace identity, self-actualization, and the misalignment of "ātman" * Everyday scenario: You are a director at a large tech company. You think, "I am a successful person; I have strong willpower." Suddenly the industry lays people off; you lose your title and instantly feel "I am nothing anymore," even sinking into depression. * Walkthrough exposure: You have taken the "five aggregates" as the self. What you take as "body and material wealth (form aggregate (色陰, rūpa-skandha))," "feelings (feeling aggregate)," "cognition and perception of social labels (perception aggregate (想陰, saṃjñā-skandha))," "your volitional construction and executive drive (volition aggregate (行陰, saṃskāra-skandha))," and "your discriminating mind (consciousness aggregate (識陰, vijñāna-skandha))" — all of these are given to you by the outside world. You have no true "sovereignty." * The ātman of nirvāṇa: It is absolute "great sovereignty." Even if your title, wealth, and even health are stripped away, you still are not defined by these arising-and-perishing dharmas. Nothing can kidnap or deprive you of your core — this is true mastery.
4. Medical aesthetics, germaphobia, health maintenance, and the misalignment of "śubha" * Everyday scenario: Contemporary people are keen on detoxification, anti-aging, and sterile environments, trying to maintain this physical body made of cells (form produced by the four great elements) in a state of absolute purity and immortality. * Walkthrough exposure: No matter how you cleanse and maintain it, this biological body will inevitably undergo metabolism, will inevitably produce excrement, and will inevitably age (this is the necessary law within the twenty-five modes of existence). Seeking purity where purity is destined not to be is futile. * The śubha of nirvāṇa: It is "purity of karma" and "purity of mind." It is the absence within your mind of the impurities of greed, hatred, and delusion; it is the complete severing of the chain of samsaric flow within the three realms.
Why Contemporary People Need It
In the contemporary era, we often swing between two extremes. One is extreme materialism: desperately making money, fighting aging, buying insurance — trying to forcibly build a worldly, counterfeit "nitya-sukha-ātman-śubha" in this impermanent world. The other is nihilism (the "lying flat" culture): when we discover that material goods and emotions cannot be relied upon, we feel "life is meaningless; in the end we are all ash," and sink into depression and giving up.
Contemporary neuroscience and evolutionary biology, to a certain extent, corroborate Buddhism's diagnosis of worldly life. Science tells us that the brain's dopamine system (the reward prediction error mechanism) was designed by evolution to: forever drive us to pursue the next goal, and once we obtain it, the pleasure rapidly decays (hedonic adaptation). This is so that in ancient times we would keep foraging and reproducing. Science clearly reveals that worldly "sukha" is in essence a treadmill that cannot be satisfied (duḥkha), but science does not provide an ultimate solution for jumping off the treadmill entirely.
(*Note: Of course, we cannot say that brain science proves the Buddhadharma. Science studies the material basis and neurotransmitters; it is a description of the phenomenal world. The Buddhadharma points to the unconditioned dharma (無為法, asaṃskṛta-dharma) and the state of liberation that transcend empirical observation. The two operate on different dimensions.*)
The concept of "nitya-sukha-ātman-śubha" exists precisely to rescue us from these two extremes. It tells you: Yes, everything in the world is indeed impermanent, suffering, no-self, and impure; you need not fish for tiles in murky water. But do not despair — the endpoint of liberation is by no means a dead, silent nothingness; there is a real jewel to be found. It provides you with an extremely safe, vast, and powerful spiritual refuge. Knowing that there is a real 常樂我淨 ahead, we can face the gains and losses of this life, birth, aging, sickness, and death with genuine composure — because you know that what you lose was never your true treasure to begin with.
Common Misreadings and Clarifications
Although this concept is beautiful, it is very easy to fall into pitfalls, and the classics have made extremely rigorous anti-counterfeiting distinctions:
Misreading One: Equating "ātman" with the "soul (puruṣa)" of other religions Many people, upon seeing Mahāyāna Buddhism speak of "self," happily say: "So Buddhism also admits there is an eternal soul hiding inside the body!" Clarification: The *Mahāparinirvāṇa-sūtra* sternly points out that although non-Buddhist traditions (other religious systems) also say "nitya-sukha-ātman-śubha" with their mouths, they are like people born blind guessing the color of milk — merely playing with words (worldly conventional speech), not understanding the true meaning. The non-Buddhist "self" is the clinging to a substantial entity above the five aggregates that can transmigrate; the Buddhist "true self" is, after completely shattering the clinging to the five aggregates, the pure state of "attaining great sovereignty" that manifests — absolutely not a concrete deity or soul-entity.
Misreading Two: Understanding "emptiness" as nothing-at-all (evil grasping of emptiness, 惡取空) Someone might ask: "Doesn't the *Prajñāpāramitā-sūtra* say 'all dharmas are empty'? How do four qualities suddenly appear?" Clarification: The sūtras contain an extremely subtle dialectic on "emptiness and non-emptiness." The so-called "empty" means that in nirvāṇa, afflictions, suffering, and the samsaric rotation of the twenty-five modes of existence are emptied out; the "non-empty" means that after pulling out these weeds, the pure nature and true qualities that manifest (nitya-sukha-ātman-śubha) genuinely and actually exist. One cannot speak only of emptiness, nor only of non-emptiness.
Misreading Three: Believing that casual practice, or attaining arhatship, will yield "nitya-sukha-ātman-śubha" Clarification: This confuses the stages of cultivation. The sūtra clearly states that although voice-hearers and solitary-realizers of the two vehicles have liberated themselves from birth and death, because the nirvāṇa they have realized does not possess the completeness of 常樂我淨, it can only be called nirvāṇa, not "Mahāparinirvāṇa" (great nirvāṇa). Only bodhisattvas who have personally seen buddha-nature can "partially see" (分見) nitya-sukha-ātman-śubha; and only the completely perfect Tathāgata can "fully see" it. This is an extremely high ultimate state that can only fully manifest after thoroughly purifying all subtle afflictions.
May this exploration help you know where the true anchor lies when facing the various impermanences and clamor of the world. When the water is murky, do not panic. Wait for the afflictions to settle — that vaidūrya jewel of nitya-sukha-ātman-śubha was, from the very beginning, at the bottom of your own mind.
