Rebirth vs reincarnation: what's the difference?

By Tim Yu · Updated 2026-06-04

Reincarnation usually means a permanent soul or self that passes intact from one body to the next. Buddhism denies any such unchanging self, so it speaks instead of rebirth: a conditioned continuity — a causal stream shaped by craving and karma — in which no soul transmigrates. The reborn being is “neither the same nor another” as the one who died.

The short answer

The two words point to different pictures of what survives death. Reincarnation typically assumes a soul or self (in Hindu thought, the ātman) that persists and moves into a new body. Rebirth, the term Buddhism prefers, denies any permanent self at all. What continues is not a thing that is handed over but a conditioned process: mind and karma giving rise to a new life that is causally linked to the old one without being identical to it. Encyclopædia Britannica frames the contrast plainly — Hinduism teaches an eternal ātman that transmigrates, whereas Buddhism “denies the existence of an unchanging, substantial soul or self” and speaks of anatman (non-self), holding instead to the transmigration of accumulated karma.

The soul question: not-self (anattā)

The distinction turns on a core Buddhist teaching: anattā, or not-self. In the Anattalakkhaṇa Sutta (SN 22.59), the Buddha examines the five aggregates that make up a person — form, feeling, perception, mental formations (or “choices”), and consciousness — and states of each that it is “not self.” In Ṭhānissaro Bhikkhu’s translation: “Form, monks, is not self… Feeling is not self… Perception is not self… [Mental] fabrications are not self… Consciousness is not self.” Bhikkhu Sujato’s rendering reaches the same point with the term “not-self.” Because not even consciousness counts as a permanent self, there is nothing in the Buddhist analysis of a person that could play the role of a soul travelling intact from life to life. This is precisely what the word reincarnation, in its ordinary meaning, assumes — and what Buddhism sets aside.

”Neither the same nor another”

How, then, can rebirth happen at all? The classic answer comes from the Milindapañha (The Questions of King Milinda), a much-loved dialogue between the monk Nāgasena and the Indo-Greek king Milinda. It is a paracanonical (post-canonical) text rather than a discourse of the Buddha himself, but it is widely respected across Theravāda tradition for exactly this kind of clarification.

Asked whether the one who is reborn is the same person as the one who died, Nāgasena answers (in T. W. Rhys Davids’ translation): “Neither the same nor another.” He illustrates the point with a lamp burning through the night — the flame in the last watch is not literally the same flame as in the first, yet the light comes from the one lamp all night through — concluding that “neither as the same nor as another does a man go on to the last phase of his self-consciousness.” (Wording follows Rhys Davids; phrasing of the simile is summarised, not quoted in full.)

John Kelly’s translation of the same passage (Miln III.5.5) gives the image even more directly: “Just as, your majesty, if someone kindled one lamp from another,” the lamp itself does not pass across — “one does not transmigrate and one is reborn.” The second flame is genuinely dependent on the first, but nothing is transferred. That is the heart of the rebirth/reincarnation distinction: real continuity, no transmigrating soul.

How rebirth works without a soul

If no self is handed over, what links one life to the next is causation, not identity. Buddhism describes existence as saṃsāra, the round of rebirth driven by craving and karma. Britannica notes that Buddhism, “which does not assume the existence of a permanent soul,” still accepts a continuity that “goes through the process of samsara,” with one’s remaining karma “having determined the circumstances of its next life.” In other words, the conditions a person creates — their intentions and actions — shape what arises next, much as one flame conditions another, without any unchanging entity persisting in between. Rebirth is a process that is conditioned, not a passenger that is transported.

A note across traditions

This is common ground rather than a sectarian quirk. Every Buddhist school rejects a permanent, transmigrating self and therefore prefers the language of rebirth to that of reincarnation; the disagreements between traditions concern how the process is best described, not whether a soul travels. Britannica’s contrast between the Buddhist anatman and the eternal ātman of Hindu thought captures the dividing line that all Buddhist schools sit on the same side of. So while “reincarnation” is often used loosely in English to cover both ideas, on a Buddhist understanding the more precise word is rebirth.
