Buddhism shares with other Indian traditions the belief in rebirth, but denies that a self passes from life to life. Instead, a causal stream of mental processes continues, as a flame is passed from candle to candle. Rebirth in heavens, the human world or lower realms follows from intentional action. Its ending is nirvāṇa.
Rebirth
The continuation of a being’s life process in a new existence after death, shaped by karma.
