The causal process of the transference of a mindstream from one life to the next. The Bhava­saṅkrānti­sūtra asserts that there is no phenomenon that actually transmigrates from one life to the next, but rebirth occurs through the causal power of actions (karma). See introduction at UT22084-063-007-25. The term may also refer to the yogic or tantric practice of deliberately ejecting consciousness from the body, but this practice is not related to the context of this sūtra.
