Does Judaism believe in reincarnation? You could say that it wrote the BOOK on reincarnation, gilgulim in Hebrew. At least Rabbi Yitzchak Luria, otherwise known as the "Arizal," did. Transcribed by his foremost student, Rabbi Chaim Vital, the eighth "gate" of the Ari's writings, "Sha'ar HaGilgulim," is not only a discussion about reincarnation, but a very detailed and intense description of personal and world rectification, not to mention an eye-opening look at Jewish history. It is an indispensable work for the person interested in personal growth and making sense of what has often been convoluted history.
