What is metempsychosis?

Metempsychosis is the philosophical and religious concept that posits the transmigration of the soul, where the soul passes into a new body after death. This idea is often associated with beliefs in reincarnation, suggesting that the soul undergoes a cycle of rebirth in different forms of life. The term has roots in ancient Greek thought and is linked to various spiritual traditions, including Hinduism and Buddhism, where it reflects the continuity of existence and the moral consequences of one's actions across lifetimes.
