Sha'ar ha-Gilgulim (Gate of Reincarnations) is Chaim Vital's record of Isaac Luria's teachings on gilgul, the transmigration of souls across multiple lifetimes. This text presents a comprehensive system of how souls descend, incarnate, fail or succeed in their missions, and return for further rectification. It includes detailed accounts of the soul-genealogies of biblical patriarchs, prophets, and rabbinic sages, tracing their reincarnations through history.
