Rebirth, or reincarnation, is the belief that after death, a person's soul or spirit is reborn into a new body. This concept is found in various religions and philosophies, including Hinduism, Buddhism, and Jainism. The cycle of birth, death, and rebirth is often seen as a way for the soul to learn and grow through different experiences. In many traditions, the circumstances of the new life are influenced by the actions (or karma) of previous lives. This means that one's behavior can affect future rebirths, leading to a continuous cycle until spiritual enlightenment or liberation is achieved.
