What This Concept Means
In the scriptures, 二十五有 (pañcaviṃśati-bhava, "twenty-five existences") represents the most detailed and exhaustive division and mapping of the grand panorama of sentient beings' saṃsāric birth and death. The term 有 (bhava, "existence") here refers to existence itself—because defiled causes are produced, karmic results of vipāka must inevitably be incurred. Cause and effect do not perish, hence it is called "existence."
In short, the "twenty-five existences" refer to the twenty-five hazardous states of existence in which sentient beings stream through birth and death within the 三界 (traidhātuka, "three realms")—the desire realm, form realm, and formless realm.
In the *Mahāparinirvāṇa Sūtra* (*大般涅槃经*), the twenty-five existences are given profoundly deep metaphors and characteristics: 1. "Dwellings" and "dangerous paths" that bind sentient beings: The existential spaces that sentient beings regard as home are, in essence, merely houses that imprison body and mind, dangerous paths littered with traps. 2. Synonymous with "impurity" and "sorrow and grief": Whether as low as hell or as high as the heavens, as long as one remains within the framework of "existence," its underlying logic cannot escape the leakage of afflictions and the sorrow and suffering brought about by impermanence and destruction. 3. The "poisonous tree of the five aggregates": The physical and mental bodies of the 五陰 (pañca-skandha, "five aggregates") (form, feeling, perception, mental formations, consciousness) that sentient beings are reincarnated into and incur within the twenty-five existences are like poisonous trees. Not only can they bring no true happiness, but they constantly harm and slay sentient beings (bringing painful feelings and afflictions).
1. The Complete Structure of the Twenty-Five Existences (Exhausting the Three Realms)
Classical scriptures finely divide the three realms into twenty-five existential realms:
* Fourteen existences of the desire realm (coarse realms filled with desire and material fetters): * Existences of the four evil destinations: the existence of hell, the existence of animals, the existence of hungry ghosts, and the existence of asuras (where suffering and hatred are deepest). * Existences of the four continents of human beings: the existence of Pūrvavideha (Eastern Continent), the existence of Aparagodānīya (Western Continent), the existence of Uttarakuru (Northern Continent), and the existence of Jambudvīpa (the Southern Continent where we reside). * Existences of the six heavens of the desire realm: the existence of the Four Heavenly Kings, the existence of the Thirty-Three Heavens (Trāyastriṃśa), the existence of Yāma, the existence of Tuṣita, the existence of Nirmāṇarati, and the existence of Paranirmitavaśavartin. * Seven existences of the form realm (realms free from desire, characterized by subtle matter and meditative absorption): * The First Dhyāna heaven and Mahābrahmā heaven: the existence of the First Dhyāna, and the existence of Mahābrahmā Heaven (specially designated as a distinct existence). * The Second Dhyāna heaven: the existence of the Second Dhyāna. * The Third Dhyāna heaven: the existence of the Third Dhyāna. * The Fourth Dhyāna heaven, Non-Perception Heaven, and Pure Abodes: the existence of the Fourth Dhyāna, the existence of non-perception (where non-Buddhists who cultivate non-perception absorption are born), and the existence of the Pure Abodes for Anāgāmins (the Five Pure Abodes where third-stage sages reside). * Four existences of the formless realm (spiritual realms transcending material forms, leaving only subtle consciousness): * The existence of boundless space, the existence of boundless consciousness, the existence of nothingness (commonly called the "sphere of nothingness"), and the existence of neither-perception-nor-non-perception (the peak of the three realms, an extremely subtle state of consciousness).
2. The Causes of Saṃsāric Circulation and the Resolution Through "Emptiness"
Why do sentient beings cycle back and forth within the twenty-five existences? The scriptures point out that sentient beings are bound by the 「無明枷」 (cangue of ignorance), revolving endlessly around the pillar of birth and death; 煩惱 (kleśa, "affliction") is like a surging river, continuously nurturing the twenty-five existences. Because greed and lust, hatred, and delusion cover their minds, sentient beings undergo various karmic retributions within them, and are thus unable to see the Buddha-nature that exists within the five aggregates.
To escape this fate, one must cultivate 「空相」 (śūnyatā-lakṣaṇa, "the mark of emptiness"). In the *Mahāparinirvāṇa Sūtra*, "emptiness" is given an extremely clear negative definition—emptiness is "the absence of the twenty-five existences, all afflictions, all suffering, all marks, and all conditioned phenomena."
3. The Twenty-Five Samādhis as the Perfect Countermeasure to the Twenty-Five Existences
The *Mahāparinirvāṇa Sūtra* proposes a profoundly impactful mapping of liberation—the Bodhisattva-Mahāsattva, abiding in the stage of fearlessness, can use the 「二十五三昧」 (twenty-five samādhis) to eliminate, one by one, the attachments and afflictions of the twenty-five existences:
* Shattering the evil destinations: Shattering the existence of hell yields the "Stainless Samādhi"; shattering the existence of animals yields the "Non-Retrogression Samādhi"; shattering the existence of hungry ghosts yields the "Mental Joy Samādhi"; shattering the existence of asuras yields the "Delight Samādhi." * Shattering the four continents: Shattering the existence of Pūrvavideha yields the "Sunlight Samādhi"; shattering the existence of Aparagodānīya yields the "Moonlight Samādhi"; shattering the existence of Uttarakuru yields the "Heat Flame Samādhi"; shattering the existence of Jambudvīpa (the human realm) yields the "Illusion-Like Samādhi". * Shattering the desire heavens: Shattering the existence of the Four Heavenly Kings yields the "Immovability of All Dharmas Samādhi"; the Thirty-Three Heavens yields the "Hard to Subdue Samādhi"; Yāma Heaven yields the "Pleasing Samādhi"; Tuṣita Heaven yields the "Blue Color Samādhi"; Nirmāṇarati Heaven yields the "Yellow Color Samādhi"; Paranirmitavaśavartin Heaven yields the "Red Color Samādhi." * Shattering the form realm: Shattering the existence of the First Dhyāna yields the "White Color Samādhi"; Mahābrahmā Heaven yields the "Variegated Samādhi"; the Second Dhyāna yields the "Dual Samādhi"; the Third Dhyāna yields the "Thunder Sound Samādhi"; the Fourth Dhyāna yields the "Torrential Rain Samādhi"; shattering the existence of non-perception yields the "Space-Like Samādhi"; shattering the existence of the Pure Abodes of Anāgāmins yields the "Mirror-Reflecting Samādhi." * Shattering the formless realm: Shattering the existence of boundless space yields the "Unobstructed Samādhi"; boundless consciousness yields the "Permanent Samādhi"; shattering the existence of nothingness yields the "Bliss Samādhi"; shattering the existence of neither-perception-nor-non-perception yields the "Self Samādhi".
Here lies an extraordinarily profound principle: even at the peak of the three realms, the "sphere of neither-perception-nor-non-perception," it remains a defiled "existence"; only by using the "Self Samādhi" (the Great Self that is truly permanent, joyful, self, and pure) to break through it can one thoroughly depart from the twenty-five existences and realize "true liberation."
4. The Dialectic of "Arriving" and "Not Arriving"
The scriptures use "arriving" and "not arriving" to define the states of ordinary beings and sages: * 凡夫 (pṛthagjana, "ordinary beings"): Driven by afflictions, wandering back and forth within the twenty-five existences like a rotating wheel, this is called "arriving". * The Two Vehicles and Bodhisattvas (the self-liberation aspect): Hearers (śrāvaka), Solitary Buddhas (pratyekabuddha), and 菩薩 (bodhisattva, "bodhisattvas") sever afflictions forever and completely transcend, which is called "not arriving". * Bodhisattvas (the compassionate aspect of saving sentient beings): In order to transform and save sentient beings, bodhisattvas voluntarily manifest within the twenty-five existences (even taking on animal bodies), which is also called "arriving". But the bodhisattva's "arriving" differs from that of ordinary beings: although bodhisattvas are within the twenty-five existences, they never create evil karma, are never defiled by the existences, and constantly expound the True Dharma for sentient beings.
A Walkthrough in Daily Life
We often assume that "reincarnation" is a distant event that only happens after death. But if we treat the twenty-five existences as a subtle spectrum of conscious experiences and modes of existence, you will find that contemporary people traverse back and forth through these twenty-five existences countlessly many times within a single day.
Let us walk through the mapping of the twenty-five existences using a scenario most familiar to contemporary people—the process of "scrolling through one's phone late at night while working overtime, up until getting up early for work the next day":
1. The Evil Destinies and Four Continents of the Desire Realm (Low-Level Emotions and Everyday Survival)
* Hell existence: Receiving criticism in a work group chat late at night, or falling into extreme anxiety and self-blame, feeling as if one's heart were roasted in searing fire or suffocated in ice. This extreme psychological suffering is the "hell existence" into which one's mind falls in that moment. * Hungry ghost existence: At 1:00 AM, frantically scrolling through short videos, compulsively shopping, or desperately craving validation and attention. No matter how much information or consumption fills it, the heart constantly feels a bottomless pit of deficiency and hunger; this is the "hungry ghost existence." * Animal existence: The brain goes completely numb, relinquishing thought and merely driven by instinct to follow recommendation algorithms, watching meaningless comedy clips episode after episode, trapped in pure ignorance and passive response; this is the "animal existence." * Asura existence: Seeing the success of peers on social media, intense jealousy, defiance, and competitiveness surge within, leading to frantic arguments and debates in the comment section; this is the "asura existence." * Jambudvīpa existence (Human Realm): The alarm rings in the early morning, rationality returns, and you wash up, brush your teeth, and commute on the subway, struggling to survive in a daily reality woven of pleasure and pain. This is the "Jambudvīpa existence" with which we are most familiar.
2. Heavenly Existences of the Desire Realm (Advanced Sensual Compensation)
* From the Four Heavenly Kings to Paranirmitavaśavartin: Deep in the night, you eat an exquisite late-night snack, listen to music on high-fidelity audio, or experience the thrill of controlling everything in a virtual game. This momentary sense of ascension and pleasure brought about by relying on external material stimuli (appetite, sexual desire, experiential desire) is the manifestation of the "Desire Realm Heavenly Existences." However, this happiness is attached to external conditions; as soon as external conditions dissipate, a sense of loss immediately strikes.
3. Existences of the Form and Formless Realms (Advanced Spiritual Escape)
The place where contemporary people are most prone to misinterpretation is mistaking higher-level spiritual states for complete liberation. * Form realm dhyāna existences (First Dhyāna to Fourth Dhyāna, and Non-Perception): You attend an intensive meditation retreat or, through breathing exercises, experience a sense of purity wherein the body is settled and inner thoughts do not arise; some even achieve a state through extreme focus where "the mind is a total blank, devoid of any stray thoughts" (similar to the "existence of non-perception"). * *Prone-to-err mapping*: Many think that "when the mind is tranquil and without stray thoughts," one has attained enlightenment and liberation. Yet in classical doctrine, this is merely a "form realm existence" or "non-perception existence." Your underlying fundamental ignorance still remains; once you leave the meditation hall and return to the chaotic workplace, this purity instantly collapses. * Formless realm existences (Sphere of Nothingness, Sphere of Neither-Perception-Nor-Non-Perception): Certain elite spiritual seekers or minimalists completely let go of attachment to matter and physical bodies, entering a philosophical meditation or spiritual realm where "heaven and earth are empty, leaving only subtle consciousness" or a state that is "seemingly perceiving yet non-perceiving, profoundly wondrous." * *Prone-to-err mapping*: This state is extremely close to what people imagine as "emptiness," making it very easy to mistake for true 涅槃 (nirvāṇa, "nirvāṇa"). However, the scriptures explicitly state that even upon reaching the "existence of nothingness" or "existence of neither-perception-nor-non-perception," it still belongs to the peak of the twenty-five existences! It is merely an advanced meditative state of consciousness; as long as ignorance is not shattered, one will still fall back into reincarnation once meditative power wanes.
Why Contemporary People Need It
The suffering of contemporary people is often not merely material scarcity, but rather exhaustion and entrapment in their state of existence. We constantly switch between various roles and states, only to find that no matter how we switch, we cannot gain eternal peace.
The concept of the twenty-five existences provides contemporary people with two extremely sharp blades of wisdom for deconstruction:
1. Exhausting All "Existential Illusions" and Shattering Attachment to High-Level States
Contemporary society is rife with elegantly packaged "spiritual sanctuaries"—from the sensory pleasures of consumerism (Desire Heavens), to the cool serenity of yoga meditation (Form Realm), and further to the transcendence of minimalism, nihilistic philosophy, or metaphysical meditation (Formless Realm). The most profound aspect of the concept of the twenty-five existences is that, like a map without blind spots, it bundles all possible states of existence (from hell to the heaven of neither-perception-nor-non-perception) into "existence." It warns contemporary people: As long as you are still seeking a certain "state" (even an extremely high-level state of purity), you are still inside the house, still beneath the poisonous tree. True liberation is not escaping from coarse experiences to refined ones, but thoroughly seeing through the impermanence and non-self of all experiences.
2. Guarding Against the "New Heavens" Constructed by Science and Technology
In the contemporary technological landscape, algorithms, the metaverse, brain-computer interfaces, and even future consciousness uploading are creating extremely realistic "Desire Heavens" or even "Formless Heavens." Humans attempt to escape the suffering of the physical body through technology (form/formless realization) and attain eternal pleasure in virtual space (desire heaven realization). However, comparing contemporary neuroscience with algorithmic life: algorithmic recommendations and neural stimulation can indeed precisely manipulate dopamine and serotonin to produce physiological pleasure similar to the desire heavens or form-realm absorptions. Yet neuroscience research also indicates that the adaptability of the nervous system (the Hedonic Treadmill effect) dictates that any pleasure based on physiological neural mechanisms will suffer diminishing returns. This precisely confirms the insight of classical Buddhism: states built upon conditioned phenomena (neurotransmitters, electrical signals, mental fabrications) are inherently unstable, subject to decay and destruction "existences." Technology can reconstruct the forms of the twenty-five existences, but it cannot create true liberation beyond the twenty-five existences out of thin air.
Common Misreadings and Clarifications
Misreading 1: Mistaking Meditative Absorptions of the Form and Formless Realms for Complete "Liberation" or "Enlightenment"
* Clarification: This is the most common misunderstanding throughout history. Many people sit in meditation to cultivate absorption, experience "sloughing off of body and mind," "merging with empty space," or "having not a single thought," and thus believe they have realized nirvāṇa. Classical doctrine strictly distinguishes between "meditative states" and "liberation through insight." The "non-perception existence" of the Form Realm, as well as the "existence of nothingness" and "existence of neither-perception-nor-non-perception" of the Formless Realm, although extremely pure, still belong to the twenty-five existences; their nature remains that of karmic fruition incurred by defiled causes. Once meditative power is exhausted, one will still drift downward along the stream. The *Mahāparinirvāṇa Sūtra* points out that only by cultivating the mark of emptiness and using the "twenty-five samādhis" to shatter attachment to these high-level states (such as using the "Self Samādhi" to shatter the existence of neither-perception-nor-non-perception) can one thoroughly escape.
Misreading 2: Thinking That Liberation Means Completely Destroying or Escaping This Physical World
* Clarification: Hearing "departing from the twenty-five existences," some assume Buddhism is a world-weary, reality-evading nihilism, or even think that one must leave Earth or eliminate the physical body. This is a narrowing of "transcendence." According to the analysis in the *Mahāparinirvāṇa Sūtra*, although bodhisattvas have eternally departed from the twenty-five existences (termed "not arriving"), they still manifest within the twenty-five existences to transform and save sentient beings (termed "arriving"). Although the 如來 (tathāgata, "Tathāgata") abides in the twenty-five existences, he is "unpolluted by the various existences." So-called "transcending the twenty-five existences" is not a spatial flight, but the mind no longer being bound by ignorance and no longer taking the body and mind of the five aggregates to be a real self, thereby maintaining great freedom and great compassion in any realm.
Misreading 3: Equating Scientific Concepts (Such as Multidimensional Space or Parallel Universes) Directly with the Twenty-Five Existences
* Clarification: In contemporary discussions, people often crudely equate the Form Realm and Formless Realm with "high-dimensional spaces" or "parallel universes" in physics. While this analogy helps with intuitive understanding, it can never be equated at the level of doctrine. High-dimensional spaces or parallel universes in physics still fall within the domain of spatiotemporal physics, essentially being the physical realm of container worlds (器世間, bhājana-loka) extending material and spatiotemporal structures. In contrast, the Buddhist twenty-five existences represent living modes of existence centered on karma, afflictions, and karmic manifestation of consciousness (the unity of the sentient realm, 情世間 / sattva-loka, and container realm, 器世間 / bhājana-loka). Science can explore dimensions of space, but it cannot explain how karma incurs ripening results. The development of science can serve as an auxiliary means to understand Buddhist metaphors, but it is by no means scientific proof of the twenty-five existences. True liberation is forever built upon the complete destruction of mental ignorance and attachment.
