Reincarnation is the belief that after death, a person's soul or consciousness is reborn into a new body or form. This concept is prevalent in various religious and philosophical traditions, including Hinduism, Buddhism, and certain New Age beliefs. The cycle of death and rebirth, known as samsara, continues until the soul achieves enlightenment or liberation. Reincarnation emphasizes the idea of karma, where one's actions in past lives influence their current and future experiences.
