Rebirth (Buddhism)

• 1. Introduction

  ›

  Rebirth in Buddhism poses a question that has occupied philosophers, monks, and ordinary people for more than two millennia: if there is no soul, what exactly comes back? That puzzle sits at the heart of one of Buddhism's most foundational teachings. The doctrine holds that the actions of a sentient being generate a new existence after death, again and again, in an endless cycle the tradition calls samsara. That cycle is described as dukkha, a Pali and Sanskrit word meaning unsatisfactory and painful. It stops only when nirvana is achieved, through insight and the extinguishing of craving.

  Rebirth is not a minor footnote in Buddhist thought. It stands alongside karma and nirvana as one of the religion's core doctrines. And yet for more than two thousand years, Buddhist thinkers have disagreed sharply about what it is in a person that actually gets reborn, how quickly that rebirth occurs, and whether there is any gap between one life and the next. Those debates have produced some of the most sophisticated philosophy in any religious tradition. They have also produced some of the most unusual funeral rituals on earth, particularly in Tibet, where the question of what happens in the days immediately after death is mapped with extraordinary precision.

• 2. A World Before the Buddha

  ›

  Long before the Buddha taught, the Indian intellectual landscape already contained several competing accounts of death and what follows. The earliest layers of the Vedas mention no doctrine of karma or rebirth at all. They describe ancestor worship and rites such as sraddha, the offering of food to deceased relatives. It was only in the later Vedic texts, the Aranyakas and the Upanishads, that a soteriology built on reincarnation emerged. By that point, the concern with ancestor rites had largely fallen away.

  The Sramana schools, which included early Jainism, affirmed the existence of a soul, karma, and a cycle of rebirth. The competing Indian materialist schools, sometimes called the Carvaka, took the opposite position: there is only one life, there is no rebirth, and death is complete annihilation. The Samaññaphala Sutta, which has a parallel at Digha Agama 27, explicitly criticizes that materialist view. According to that sutta, to hold that all beings are destroyed at death, at a time when the Buddha's teachings are available, is equivalent to being born dumb and dull.

  The Buddha drew from this crowded field selectively. He accepted rebirth and karma while rejecting both the materialist denial and the Hindu and Jaina assertion of an unchanging soul. His key innovation was the concept of anatta, or not-self: the claim that there is no fixed, eternal entity riding from life to life. He also affirmed that all compounded things are subject to dissolution at death, a principle called anicca. These two positions set up the central philosophical tension that Buddhist thinkers would wrestle with for centuries: how can there be continuity across lives if there is nothing that persists?

• 3. The Mechanics of Passing On

  ›

  Early Buddhist texts describe the rebirth process with precise and sometimes surprising detail. According to the scholar Damien Keown, the early scriptures record that on the night of his awakening, the Buddha gained the ability to recall a vast number of past lives, along with details about them. The Majjhima Nikaya reports he could remember as far as ninety-one eons into the past.

  The early texts use a striking comparison to explain how consciousness moves between lives. An analogy drawn from Anguttara Nikaya 7.52 compares the process to a spark leaping from a hot piece of iron through the air. The key point is that nothing literally travels; a causal process transfers. Dirgha Agama 13 and its parallels push this further, quoting the Buddha directly: if consciousness did not enter the mother's womb, would there be name and form? Ananda replied: no. The same text states that if consciousness were to depart from the womb, the fetus could not continue to grow.

  The early texts also describe what is being transferred as not a blank slate. The rebirth consciousness carries underlying tendencies called anusaya, which form a condition for continued rebirth and carry imprints from past lives. A separate early term, gandhabba, translated roughly as spirit, also appears. The Assalayana Sutta and its parallel at Madhyama Agama 151 state that for conception to be successful, a gandhabba must be present alongside other physiological factors. The Kutuhalasala Sutta provides the most explicit early reference to a gap between lives: when a being has laid down one body but has not yet been reborn in another, it is, the text says, fuelled by craving.

• 4. Six Realms, Merit, and the Four Stages

  ›

  Traditional Buddhist cosmology maps rebirth across six distinct realms: the Deva realm of heavenly gods, the Asura realm of demi-gods, the human realm, the animal realm, the ghost realm called Preta, and the hellish realms called Naraka. The realm a being enters is conditioned by the karma accumulated in current and previous lives. Kusala karma, meaning good or skillful action, leads toward the better realms. Akusala karma, the unskillful variety, steers a being toward the more painful ones.

  While nirvana remains the ultimate goal of Buddhist teaching, the tradition acknowledges that most practitioners spend their lives working toward better rebirths rather than final liberation. Much of traditional Buddhist practice has centered on gaining merit and transferring it, so that individuals or family members might secure a favorable next life.

  The path toward full liberation passes through four recognized stages of awakening. A Sotapanna, or stream-enterer, still faces up to seven more rebirths. A Sakadagami, or once-returner, will undergo only one more human rebirth. An Anagami will return one final time, but only to a heavenly realm. An Arahant has cut off rebirth entirely and will not be reborn in any realm. With each of these stages, certain mental defilements described as fetters are abandoned, drawing the practitioner progressively closer to the end of the cycle that the doctrine calls samsara.

• 5. What Exactly Gets Reborn

  ›

  After the Buddha's death, the Buddhist schools that emerged debated the rebirth mechanism with remarkable intensity. The early texts sometimes speak of a stream of consciousness, using the Pali phrase viññana sotam, as that which transmigrates. But according to scholar Bruce Matthews, there is no single major systematic exposition on this subject in the Pali Canon.

  Several distinct theories emerged. The Sautrantika, Mahasamghika, and Mahasisaka schools explained karmic continuity through a seed theory: each personal action perfumes the individual stream of consciousness and plants a seed that later germinates as a good or bad karmic result. The influential philosopher Vasubandhu defended this seed theory in his Abhidharmakosha. Asanga's Mahayanasanghraha developed it further into the Yogacara doctrine of the alaya-vijñana, or container consciousness, a subliminal and constantly changing stream that stores karmic seeds and undergoes rebirth. Asanga noted that the Mahasamghika schools called this the root-consciousness, and that the Sthavira schools referred to it as the bhavanga.

  The Sarvastivada-Vaibhasika school rejected the seed theory. Since they held that phenomena in the past, present, and future all exist, they argued that a performed action continues to exist in a state of possession relative to the mindstream of the person who acted. The Prasangika branch of the Madhyamaka school, exemplified by Chandrakirti, went further and attempted to refute every concept of a storehouse of karmic information, including the alaya-vijñana, arguing instead that a karmic action results in a potential that needs no support to ripen.

  A now-defunct school called the Pudgalavada took a different approach entirely. It accepted that there is no atman, but asserted a personal entity called pudgala that retains karmic merit and migrates from life to life. This entity was held to be neither identical to nor different from the five aggregates. The concept drew heavy criticism from Theravada Buddhists in the early first millennium CE and was rejected by the Pali scholar Buddhaghosa, who also rejected it from his own Theravada framework.

• 6. The Debate Over the Gap Between Lives

  ›

  One of the sharpest disputes in Indian Buddhist philosophy concerned whether anything at all exists in the interval between death and rebirth. Andre Bareau's survey of the Indian schools shows a clear division. The Sarvastivada, Sautrantika, Pudgalavada, Purvashaila, and late Mahishasaka schools accepted an intermediate existence, called antarabhava. The Mahasamghika, early Mahishasaka, Theravada, Vibhajyavada, and the school associated with the Sariputrabhidharma rejected it, holding that consciousness leaps immediately from one body to the next.

  Vasubandhu, in the Abhidharmakosha, defended the intermediate state at length. He argued that the being in this interval is composed of all five aggregates, arises at the place of death, and carries the configuration of the future being. He added a peculiar detail: this conscious intermediate being becomes aroused on seeing its future parents joined in intercourse, becomes envious of one parent, and through that desire and hatred attaches itself to the womb where it conditions the first moment of birth existence.

  Tibetan Buddhism developed the most elaborate account of this interval. The bardo, as it is called in Tibetan, is described as a period involving visions of peaceful and wrathful deities, and texts like the Bardo Thodol provide detailed maps for navigating it. Some Tibetan traditions hold that this intermediate period may last as long as forty-nine days, and the funerary rituals that grew from this belief are among the most distinctive in any religious tradition.

  Buddhaghosa, writing from the Theravada perspective, dismissed the intermediate state entirely. In his account, the very last moment of consciousness at death, the cuti viññana, conditions the very first instant of consciousness in the next life, the patisandhi viññana, which arises at conception. He compared their relationship to a seal pressed into wax: the impression is caused by the seal but is not the same entity as the seal. Nothing travels. Yet even within the Theravada world, the Burmese monk Balangoda Ananda Maitreya and many lay practitioners have defended the idea of an interim state, commonly referred to as the gandhabba or antarabhava.

• 7. The Case for Rebirth

  ›

  Buddhist philosophers developed three distinct lines of argument for the truth of rebirth: empirical, metaphysical, and pragmatic.

  On the empirical side, ancient Buddhist thinkers pointed to the Buddha's own reported ability to recall past lives and to access the past-life memories of other beings, as described in texts like the Bhayabherava Sutta and the Mahapadana Sutta. The 8th-century Indian philosopher Santaraksita argued in his Tattvasamgraha that newborn children exhibit complex desires, emotions, and mental states that could not exist without habits acquired in a past life. Modern figures including Bhikkhu Analayo and B. Alan Wallace have pointed to near-death experiences, past-life regression research, and the work of American psychiatrist Ian Stevenson as potential empirical evidence.

  The metaphysical argument was most fully developed by Dignaga, who lived roughly from 480 to 540 CE, and Dharmakīrti, who flourished in roughly the 6th or 7th century. In his Pramanavarttika, Dharmakīrti argued against the Carvaka claim that consciousness is simply a byproduct of the body. His key premise was that every event must be preceded by an antecedent causal condition of the same class. Since mental events must have prior mental events as their cause, the chain stretches back before birth into a previous life. The philosopher Evan Thompson summarized Dharmakīrti's core point: matter and consciousness have totally different natures; an effect must be of the same nature as its cause; hence consciousness cannot arise from matter alone.

  The American monk Thanissaro Bhikkhu has articulated a pragmatic argument that draws on a passage in Majjhima Nikaya 60, the Apannaka Sutta, where the Buddha describes his teaching as a safe bet. If there is an afterlife, those who perform bad actions have made a bad throw twice, since they are harmed in both this world and the next. If there is no afterlife, those who acted well lose nothing by having lived carefully. The Kalama Sutta develops a related argument that the tradition calls the four assurances, each of which offers a reason why accepting rebirth leads to a better outcome regardless of whether it is literally true.

• 8. Dissent, Reinterpretation, and Comparison

  ›

  Not every thinker in the Buddhist tradition has accepted a literal reading of rebirth. In the 1940s, J. G. Jennings argued that the doctrine of anatta is incompatible with the idea that one individual's actions can have repercussions for the same individual in a future life. He proposed reading rebirth as the recurrence of selfish desires across endless succeeding generations, with consequences that are collective rather than individual.

  The Thai modernist monk Buddhadasa, who lived from 1906 to 1993, went further. He argued that since there is no substantial self or soul, in the ultimate sense there is no one born and no one who dies and is reborn, and that therefore the whole question of literal rebirth is, in his words, quite foolish. His alternative reading located rebirth not in a future womb but in the re-arising of the sense of self, an ego-centredness born from ignorance, craving, and clinging. The British Buddhist thinker Stephen Batchelor has offered a less metaphysical version of a similar view, suggesting that regardless of personal survival, the legacy of one's thoughts, words, and deeds will continue through impressions left in the lives of those one has influenced.

  Among the major Indian traditions, both Hinduism and Jainism accept karma and rebirth but do so from very different foundations. Hindu traditions rest on the assumption that an eternal soul, the atman, exists and in many schools is identical with Brahman, the ultimate reality. Jainism accepts a soul called jiva and holds that the rebirth cycle has a definite beginning, that karmic particles physically adhere to the soul, and that some souls are permanently incapable of achieving liberation. Both traditions share with Buddhism a belief in realms of birth and an ethical framework oriented toward a good rebirth. The difference lies entirely in what they believe is doing the traveling, and the Jaina concept of karmic matter as literal particles sticking to the soul stands at the furthest remove from the Buddhist account in which nothing, strictly speaking, transmigrates at all. Buddhaghosa's image of the seal and the wax remains the classic encapsulation of that difference.
