In Buddhism, samsara (Pali and Sanskrit saṃsāra) means the round of birth, death and rebirth. The early texts say no first point of it can be found, and that beings wander in it “shrouded by ignorance and fettered by craving” (SN 15.1, trans. Bhikkhu Sujato). Samsara is a process rather than a place, and it can end: the Pali discourses call its ending nibbāna, in Sanskrit nirvāṇa.

It is one of the core teachings of Buddhism, bound up with the noble truths, karma and dependent origination, each covered below. See also the glossary entry saṃsāra.

What does samsara mean in Buddhism?

The glossary of 84000 (Translating the Words of the Buddha) defines saṃsāra as “a state of involuntary existence conditioned by afflicted mental states and the imprint of past actions, characterized by suffering in a cycle of life, death, and rebirth.” When it is reversed, nirvāṇa is attained, “free from suffering and the processes of rebirth.”

The Pali discourses describe it with two verbs. Beings are sandhāvataṁ saṁsarataṁ: “roaming and transmigrating” in Bhikkhu Sujato’s English, “transmigrating & wandering on” in Ṭhānissaro Bhikkhu’s, and Sujato translates the noun itself as “transmigration”. The round has no findable beginning; it runs on ignorance and craving, with past action (karma) shaping each new life; and it takes in every destination, the heavens included, where even the highest gods live for vast but finite periods.

Samsara, then, is not a separate world but the cycle of which this life is one turn. What carries over from one rebirth to the next is taken up below and on rebirth vs reincarnation.

The word: meaning, root and spelling

The Pali Text Society’s Pali-English Dictionary derives saṃsāra from the verb saṃsarati (saṃ + sarati, from the root sṛ), “to move about continuously, to come again and again” and “to go through one life after the other, to transmigrate”, and glosses the noun “transmigration, lit. faring on”. Monier-Williams’s Sanskrit dictionary gives “going or wandering through, undergoing transmigration”, and the root sṛ itself means “to run, flow, speed, glide, move, go”. The popular glosses are therefore half right: wandering is in the definition of the word, while flowing belongs to its root. The Pali dictionary also lists saṃsāra-cakka, the wheel of transmigration; for the painted wheel, see the Wheel of Life.

With diacritics the word is saṃsāra (Monier-Williams, 84000) or saṁsāra (SuttaCentral’s Pali text), and the Pali Text Society dictionary online prints saŋsāra. However it is written, the nasal is the sign Pali grammar calls the niggahīta; this site, like Britannica, prints plain samsara.

Pronunciation guides give rules for the letters rather than for this one word. The ā is long: in a Thai-tradition chanting guide “the sound ā is held for approximately twice as long as the sound a”. The nasal has no single sound. That guide gives it as “ng”; Charles Duroiselle’s Pali grammar, written for students in Rangoon (its first preface is dated 1906), says the niggahīta is “pronounced like m in, jam, ram” in Burma, while “in Ceylon, it is given the sound of ng in, bring, king”. For the whole alphabet, see how to pronounce Pali and Sanskrit.

No known beginning: the Discourses on the Unknowable Beginning

The early discourses gather the theme in SN 15, the Anamataggasaṁyutta, which SuttaCentral titles “Linked Discourses on the Unknowable Beginning”: twenty short discourses. Sujato resolves the key word, anamatagga, as “no known beginning”. Many of the discourses open with the same refrain:

Each discourse then gives the scale a single image:

The eon of SN 15.5 is the Pali kappa; see kalpa. The refrain draws the conclusion: “This is quite enough for you to become disillusioned, dispassionate, and freed regarding all conditions.” In SN 15.13 it does its work: while the discourse was being spoken, “the minds of the thirty mendicants from Pāvā were freed from defilements by not grasping.”

Samsara is suffering: the ocean of tears

In the Pali canon, the noble truth of suffering begins with rebirth: “Rebirth is suffering; old age is suffering; illness is suffering; death is suffering” (SN 56.11). The Assu (“Tears”) Sutta turns that truth into one image:

The good destinations do not escape the verdict: the gods of the lower heavens, too, will die, however pleasant their lives. For the truth of suffering itself, see the four noble truths, the glossary entry dukkha, and why do we suffer?

What keeps the wheel turning

The refrain of SN 15 names two drivers, ignorance and craving. The Buddha’s first discourse defines craving (taṇhā) as “the craving that leads to future lives”, in three kinds: “craving for sensual pleasures, craving for continued existence, and craving for nonexistence” (SN 56.11). Past action is the third element, the “imprint of past actions” in 84000’s definition, and this is where karma comes in.

The Pali discourses analyse the whole mechanism as dependent origination, a series of twelve links. SN 12.1 runs the chain from “Ignorance is a requirement for choices” to its end: “Continued existence is a requirement for rebirth. Rebirth is a requirement for old age and death, sorrow, lamentation, pain, sadness, and distress to come to be.” Undo the first link and the chain comes apart: “When ignorance fades away and ceases with no residue left behind, choices cease” (SN 12.17).

What travels the round is the question every account has to answer, because the Pali discourses teach not-self (anattā). Asked by the naked ascetic Kassapa whether suffering is made by oneself or by another, the Buddha rejects both. To hold that “he who does the deed and he who experiences the result are one and the same” implies eternalism; to hold that they are different implies annihilation; “Avoiding these two extremes, the Realized One teaches by the middle way”, and what follows is the chain of conditions (SN 12.17). The Milindapañha puts it in one line: “one does not transmigrate and one is reborn”, as one lamp is kindled from another (III.5.5, trans. John Kelly). The English can mislead here: “transmigration” renders saṃsāra in Sujato’s translation, while the word the Milindapañha denies is saṅkamati, “to transmigrate, pass over” in Kelly’s note.

Encyclopaedia Britannica’s entry on saṃsāra puts the Buddhist position in its own terms. Buddhism, it says, “which does not assume the existence of a permanent soul, accepts a semipermanent personality core that goes through the process of samsara.” That phrase is Britannica’s, and not every Buddhist school would accept it. The Theravāda Abhidhamma treats dhammas as the ultimate constituents of experience and denies any being or person apart from them: “There is nothing else, whether a being, or an entity, or a man or a person,” runs a Pali commentary (Dhs-a 155), a statement aimed at the rival Pudgalavāda, “those who affirm the existence of the person”.

Where the wandering leads: the realms

The Pali discourses name five destinations (gati): “Hell, the animal realm, the ghost realm, humanity, and the gods” (MN 12). In this list the titans (asuras) are counted with the gods; the Chinese parallel to MN 12, like later traditions, makes them a separate realm, the sixth (Sujato’s note to MN 12). For the six-realm map, see the six realms; for the ghost realm, hungry ghosts. References scattered through the suttas give as many as thirty-one planes or realms, mapped on the 31 planes of existence.

Which destination a being reaches depends on action: beings are born into a particular realm according to their past kamma. Are the realms places or states of mind? Some modern teachers read the six realms “as a psychological process unfolding in this one life”, but, as the Stanford Encyclopedia of Philosophy puts it, “historically, most Buddhists have taken this system literally”. See are the realms literal or psychological? and, for the wider cosmos, Buddhist cosmology.

The way out: ending the rounds

Because samsara runs on ignorance and craving, the discourses place its end in theirs. The Sanskrit nirvāṇa literally means “extinguishment”: the cessation of suffering, of the afflictions and of the causal processes “that lead to rebirth and suffering in cyclic existence” (84000). In the first discourse the Buddha describes his own freedom in these terms: “My freedom is unshakable; this is my last rebirth; now there’ll be no more future lives” (SN 56.11). In the second, the Anattalakkhaṇa Sutta, a disciple who has been freed understands: “Rebirth is ended, the spiritual journey has been completed, what had to be done has been done, there is nothing further for this place” (SN 22.59). The method is the noble eightfold path, and one who completes it is an arahant.

The end can also come in stages. One who has ended three fetters is a stream-enterer, “not liable to be reborn in the underworld, assured, destined for awakening” (AN 3.86). The next discourse sets the outer limit: “With the ending of three fetters they have at most seven rebirths”, transmigrating “at most seven times among gods and humans” (AN 3.87). The closing verse of SN 15.10 makes the same promise to one who sees the noble truths: “After roaming on seven times at most, / that individual / makes an end of suffering”. See stream-entry and the four stages of enlightenment.

Two verses of the Dhammapada are, according to the commentary, the Buddha’s “Song of Victory”, “his first utterance after his Enlightenment” (note to Buddharakkhita’s translation):

The same note decodes the image: “The house is individualized existence in samsara, the house-builder craving, the rafters the passions and the ridge-pole ignorance.”

Samsara across the traditions

The traditions share the picture of the round, but they describe the way out of it differently.

Theravāda. The ideal of Theravāda is the arahant, the perfected saint. The life in which someone becomes an arahant is their last: they will not be reborn, but enter nirvana at death. The Theravāda tradition holds that buddhas, too, pass into nirvana at death.

Mahāyāna. In Jonathan Silk’s account for Britannica, “the application of merit toward the acquisition of wisdom and ultimate awakening, instead of toward better future rebirths within samsara, is a Mahayana innovation.” The bodhisattva, in 84000’s standard definition, will “purposely opt to remain within cyclic existence in order to liberate all sentient beings”. Mature Mahāyāna traditions tend to hold that buddhas, even after death, go on manifesting within cyclic existence until all beings are liberated. The goal of the path is a buddha’s “nonabiding nirvāṇa (apratiṣṭhitanirvāṇa), which transcends the extremes of saṃsāra and nirvāṇa, i.e., existence and peace” (84000).

Nāgārjuna. In the Mūlamadhyamakakārikā (25.19–20 in the Sanskrit text), Nāgārjuna (ca. 150–250 CE) denies any difference between saṃsāra and nirvāṇa. Kenneth Inada’s translation of the second verse, as quoted in the Stanford Encyclopedia, reads: “The limits (i.e., realm) of nirvāna are the limits of samsāra. Between the two, also, there is not the slightest difference whatsoever.” Interpreters read the claim through emptiness. For Douglas Berger there is no difference “owing to the emptiness and constantly changing nature of both”; for Bret Davis, writing on the Kyoto School, nirvāṇa is then “neither a nihilistic extinction of nor a transcendent escape from the phenomenal world (samsāra)” but “an enlightened manner of being-in-the-world here and now”.

Pure Land. The bodhisattva Dharmakara vowed to become the Buddha Amitābha, to create the world-realm Sukhāvatī (“Pure Bliss”), and to guarantee that ordinary beings could be reborn there through faith in him alone, instead of reentering the cycle of transmigration. Here the way out of samsara begins with a rebirth.

Tibetan Buddhism. The Vajrayāna, practised in Tibet and across the Himalayas, shares the Mahāyāna aim of buddhahood for the benefit of all beings. Tibetan practice also draws on teachings on the bardos. The Root Verses on the Six Bardos, from the terma of Karma Lingpa, name six: the bardos of this life, of dreams, of samādhi, of dying, of dharmatā and of becoming. The last three run from dying, when one is “about to leave this compound body of flesh and blood”, to the bardo of becoming, where the verse turns to rebirth itself:

The text closes by calling itself the “root verses of Liberation Upon Hearing in the Bardo”; see the Tibetan Book of the Dead.

Beyond Buddhism. Saṃsāra is not only a Buddhist word. Britannica’s entry opens with it as “the central conception of metempsychosis” in Indian philosophy, in which “the soul, finding itself awash in the “sea of samsara,” strives to find release (moksha)”. In Jain thought, souls accumulate karma, understood as a kind of matter, and that accumulation draws them back into a body after death. The Buddhist accounts part company on the soul.
