What the doctrine claims
Rebirth — Sanskrit punarjanma, punarbhava; Pāli punabbhava, coming-to-be again — is the claim that something of what one ordinarily takes oneself to be continues across the death of one body and the appearance of another. The orthodox Hindu reading takes the *ātman*, the unborn and undying self, as the carrier: each life is a costume the same wearer puts on, and liberation (*mokṣa*) is the recognition that the wearer was never identical with any of the costumes. The Jain reading retains the doctrine of an eternal individual jīva but treats its bondage as literal — the soul is bound by accumulated karmic matter (kārmaṇa-pudgala) which can only be exhausted by ascetic purification, and the cycle is correspondingly long and the path correspondingly arduous. The Buddhist reformulation is the most philosophically distinctive: there is no persisting ātman to be reborn — the doctrine of *anattā*, not-self — and yet rebirth occurs. What crosses is not a soul but a stream of conditioned aggregates (*skandhas*) whose causal continuity is described by the twelve-link chain of *pratītyasamutpāda*. The candle-flame image the suttas use is the standard one: the flame at the second moment is neither the same flame nor a different flame as the flame at the first; it is conditioned arising, no more and no less.
How the path-traditions use it
The functional importance of the doctrine in the path-traditions is that it gives the ethical mechanism of *karma* somewhere to land. Without rebirth the law of action and consequence is bounded by the lifespan of a single body, and the obvious cases in which evil prospers and good is unrewarded count as decisive counter-evidence. With rebirth, the accounting can extend across what the Hindu tradition counts in kalpas and the Buddhist in aeons, and the apparent injustices of any single life are reframed as moments in a longer ledger. The doctrine also gives the path itself a destination on a scale large enough to motivate the long forms of practice the traditions prescribe — the Jain ascetic curriculum, the Theravāda four-stage progression of stream-enterer → once-returner → non-returner → *arahant*, the Mahāyāna bodhisattva's vow to remain in *saṃsāra* until all beings are liberated. Several of these path-architectures are structurally unintelligible without the rebirth premise that holds the timeline open.
Where it surfaces in the index
Paramahansa Yogananda's *Autobiography of a Yogi* is the index's clearest English-language presentation of rebirth in the orthodox Hindu register: the doctrine is taken as a working assumption of the practice rather than as a thesis to be argued, and the book's recurring stories of multi-life spiritual continuity are presented as ordinary phenomena within that framework. Sadhguru's *Inner Engineering* reads the same Indian inheritance through a southern-Śaiva yogic register: the energetic body and the residual vāsanās (latent tendencies) are the load-bearing concepts, and the ledger across lifetimes is understood as carried by them. Nisargadatta Maharaj's *I Am That* takes the more philosophical position the Advaita Vedānta tradition reaches: at the level of the I am, rebirth describes the self-image's recurrence rather than a substantial soul's continuation, and the practice the dialogues recommend is the dissolution of the I am before the question of what is reborn becomes load-bearing. On the Buddhist side, Pema Chödrön's *When Things Fall Apart* and her course on awakening compassion operate inside the Tibetan Vajrayāna assumption that rebirth is real and that bodhicitta is the orientation of one's coming lives as much as of the present one; Thich Nhat Hanh on emptiness, signlessness and aimlessness and the Plum Village teaching use interbeing to reframe the rebirth question — what is reborn at any moment is the conditioned arising the present moment is also reborn into. Ram Dass's late teaching, recorded as he was visibly aging, treats rebirth as a working assumption of his Hindu bhakti lineage rather than as the topic of argument. The near-death experience literature the index also carries works the question from a different angle — empirical reports of post-mortem awareness — without resolving the doctrinal difference between the ātman-bearing and anattā-compatible readings.
What it isn't
Rebirth, in the registers the path-traditions actually use, is not a doctrine of personal soul-persistence in the popular Western sense — that the same individual ego picks up where the last life ended, with continuous memory and stable identity. The Hindu reading gives soul-persistence to the *ātman* but explicitly denies it to the ahaṅkāra (the I-maker), and the ātman the doctrine asserts is by definition without the personal-identity content the popular usage requires. The Buddhist reading gives the question its sharpest form: what is reborn is not a self because there is no self in either life, and the stream of conditioned aggregates the doctrine describes is precisely the stream the ordinary self-image is the most persistent reification of. Rebirth is also not a doctrine the contemporary contemplative-practice traditions treat as a precondition for practice: the MBSR curriculum, Adyashanti's instructions, and most of the non-dual stream operate without requiring assent to the cosmographic claim, on the grounds that the moment-to-moment reproduction of self-grasping the doctrine describes is also a description of the second-by-second loop the present-moment practice is engaging directly. Whether the cosmographic and the moment-to-moment registers are different things or different scales of the same thing is not a question the path-traditions themselves agree on, and it is the place at which their otherwise convergent practices most visibly diverge.
