The Universality of Reincarnation Beliefs
The belief that consciousness survives physical death and is reborn into new bodies, known as reincarnation, transmigration, or metempsychosis, is among the most widespread and enduring ideas in human religious and philosophical history. A survey by Walter and Waterhouse (1999) found that approximately 20-25% of adults in Western countries express belief in reincarnation, a remarkable figure given that it is not a mainstream doctrine in Christianity or Islam.
In cultures with Hindu, Buddhist, or indigenous religious foundations, the percentage is considerably higher, often representing the default assumption about the nature of consciousness and death.
Reincarnation in Major Religious Traditions
Hinduism: Reincarnation (samsara) is a central doctrine of Hindu philosophy, appearing as early as the Brihadaranyaka Upanishad (c. 700 BCE), which describes the soul (atman) as imperishable and reborn according to the quality of its actions (karma).
The Bhagavad Gita (c. 200 BCE) contains perhaps the most famous expression of this idea: "As a person puts on new garments, giving up old ones, the soul similarly accepts new material bodies, giving up the old and useless ones" (2
22). Hindu traditions describe a cycle of birth, death, and rebirth through various forms of existence (human, animal, divine, demonic) until the soul achieves moksha, liberation from the cycle through spiritual realization (Flood, 1996).
Different Hindu philosophical schools conceptualize reincarnation differently. Advaita Vedanta (non-dualism) views the individual soul as ultimately identical with Brahman (universal consciousness), making reincarnation a play of illusion (maya).
Dvaita Vedanta (dualism) maintains the eternal distinctness of individual souls. Samkhya philosophy describes the transmigrating entity as the subtle body (sukshma sharira) rather than a soul per se (Larson, 1979).
Buddhism: The Buddhist concept of rebirth (punarbhava) is philosophically distinct from Hindu reincarnation. Buddhism denies the existence of a permanent, unchanging soul (anatta/anatman), instead describing consciousness as a continually changing stream of momentary mental events.
What is "reborn" is not a soul but a continuity of karmic conditioning, often compared to a flame being passed from one candle to another: the flame is neither the same nor entirely different (Harvey, 1990).
The Tibetan Buddhist tradition developed the most elaborate practical engagement with rebirth through the institution of tulkus, recognized reincarnations of spiritual masters. The Dalai Lama lineage, the Karmapa lineage, and hundreds of other tulku lineages represent a living institutional framework for identifying and confirming reincarnated individuals, involving specific tests, divination, and recognition of objects from previous lives (Mackenzie, 1988).
Jainism: Jain philosophy provides one of the most detailed cosmological frameworks for reincarnation, describing the soul (jiva) as passing through 8,400,000 different forms of existence across four categories: infernal beings, animals and plants, humans, and celestial beings. The soul's trajectory through these forms is determined by karma, understood in Jainism as a literally physical substance that adheres to the soul (Jaini, 1979).
Ancient Greek Philosophy: Belief in metempsychosis was held by several major Greek philosophical traditions. Pythagoras (c. 570-495 BCE) reportedly taught that souls transmigrate into new bodies, and claimed to remember his own previous lives.
Plato (c. 428-348 BCE) incorporated reincarnation into his philosophical system, most notably in the Myth of Er (Republic, Book X), where souls choose their next lives before drinking from the River of Forgetfulness (Lethe) and being reborn.
Plato's concept of anamnesis, the idea that learning is actually the recollection of knowledge from previous lives, represents a philosophical integration of reincarnation with epistemology (Long, 1948).
Celtic and Norse Traditions: Several ancient European cultures held reincarnation beliefs. Julius Caesar reported that the Druids taught the transmigration of souls (De Bello Gallico, VI
14). Norse mythology describes certain forms of rebirth, particularly within family lineages, and the practice of naming children after recently deceased relatives may reflect beliefs about familial soul return (Ellis Davidson, 1964).
West African and Afro-Caribbean Traditions: The Yoruba concept of atunwa ("coming back to life") describes the rebirth of ancestors within the family lineage. Divination at birth determines which ancestor has returned, and the child may be named accordingly (Abimbola, 1976).
Similar beliefs are found in Igbo, Akan, and other West African traditions, and have been carried to the Americas through the African diaspora.
Academic Research: The Work of Ian Stevenson
The most rigorous academic investigation of reincarnation claims was conducted by Ian Stevenson (1918-2007), Carlson Professor of Psychiatry at the University of Virginia School of Medicine. Over a career spanning more than four decades, Stevenson investigated over 2,500 cases of children who spontaneously reported memories of previous lives, publishing his findings in peer-reviewed journals and detailed case study volumes (Stevenson, 1966, 1974, 1997, 2001).
Stevenson's methodology involved:
- Identifying children (typically aged 2-7) who made specific, verifiable claims about a previous life
- Recording these claims before verification was attempted
- Traveling to the location of the claimed previous life to verify details
- Documenting physical evidence (birthmarks, birth defects) corresponding to injuries on the claimed previous person
- Interviewing multiple witnesses from both families
Key findings from Stevenson's research include:
- The median interval between the death of the previous person and the birth of the child was approximately 15 months
- Many children displayed behaviors (phobias, preferences, skills) consistent with the previous person's life
- In 225 cases, birthmarks or birth defects on the child corresponded to wounds (often fatal) on the previous person, documented by medical records or autopsy reports (Stevenson, 1997)
- Cases were found across cultures, though most came from societies where reincarnation is culturally accepted
- Children typically stopped speaking of previous life memories between ages 5 and 8
Stevenson's work has been both praised for its meticulous documentation and criticized on methodological grounds. Skeptics have noted potential issues including: interviewer expectancy effects, the role of cultural expectations in shaping children's narratives, the possibility of cryptomnesia (hidden memory of information acquired through normal channels), and the difficulty of ruling out fraud in cases investigated after initial claims were already public (Edwards, 1996; Angel, 2015).
Stevenson himself was careful to frame his conclusions conservatively, stating that his cases were "suggestive of reincarnation" rather than proving it. His successor at the University of Virginia, Jim Tucker, has continued this research program, including cases from the United States and other Western cultures where reincarnation is not culturally expected (Tucker, 2005, 2013).
Brian Weiss and Regression Therapy
Psychiatrist Brian Weiss, Chairman of Psychiatry at Mount Sinai Medical Center in Miami, unexpectedly encountered past life material during a hypnotherapy session with a patient in 1980. His subsequent book "Many Lives, Many Masters" (1988) became an international bestseller and popularized past life regression therapy, a technique in which hypnosis is used to access claimed memories of previous lives.
Weiss reported that patients who underwent past life regression frequently experienced resolution of chronic physical symptoms, phobias, and relationship patterns that had resisted conventional treatment. He proposed that traumatic experiences from previous lives could create psychological patterns that persist across incarnations, and that conscious recall of these experiences could facilitate healing (Weiss, 1988, 1992).
Past life regression therapy remains controversial within mainstream psychiatry and psychology. Critics note that hypnosis is well known to produce confabulation (the creation of detailed false memories) and that subjects under hypnosis are highly susceptible to suggestion (Lynn et al
, 2003). The American Psychological Association does not recognize past life regression as an evidence-based therapy. However, some therapists report clinical utility in the technique regardless of whether the "memories" are historically accurate, viewing them as psychologically meaningful narratives generated by the unconscious mind (Woolger, 1987).
Cultural Prevalence and Psychological Function
The near-universality of reincarnation beliefs across human cultures raises interesting questions about their psychological and social functions, independent of their literal truth:
Grief and Continuity: Reincarnation beliefs provide comfort in the face of death, particularly the death of children. Anthropological research shows that in cultures with strong reincarnation beliefs, grief processes differ from those in cultures emphasizing a single life, with the expectation of reunion through rebirth moderating acute grief responses (Obeyesekere, 2002).
Moral Framework: The doctrine of karma linked to reincarnation provides a comprehensive moral framework in which all actions have consequences, even if those consequences manifest across lifetimes. This creates a powerful incentive structure for ethical behavior that does not depend on external enforcement (Keyes & Daniel, 1983).
Identity and Meaning: Past life narratives, whether understood literally or symbolically, can provide individuals with a sense of expanded identity and deeper meaning. Narrative psychologists have noted that past life stories often serve therapeutic functions similar to other forms of mythic self-narrative, helping individuals make sense of otherwise inexplicable feelings, talents, or challenges (Kramer et al , 2012).
Archetypal Resonance: From a Jungian perspective, past life imagery may represent encounters with archetypal material from the collective unconscious rather than literal historical memories. The archetypes of the warrior, the healer, the scholar, and the explorer that appear in past life narratives correspond to universal human potentials that transcend individual biography (Woolger, 1987).
