Q: like if you dye, is it true that u can come back alive without remembering your last life, and live with a new family?
A: That depends on you own belief. Belief in reincarnation is an ancient phenomenon. This doctrine is a central tenet within the majority of Indian religious traditions, such as Hinduism (including Yoga, Vaishnavism, and Shaivism), Jainism, and Sikhism. The idea was also entertained by some ancient Greek philosophers. Many modern Pagans also believe in reincarnation as do some New Age movements, along with followers of Spiritism, practitioners of certain African traditions, and students of esoteric philosophies such as Kabbalah, Sufism and Gnostic and Esoteric Christianity. The Buddhist concept of Rebirth although often referred to as reincarnation differs significantly from the Hindu-based traditions and New Age movements in that there is no "self" (or eternal soul) to reincarnate.
