 The Master Hilarion is believed to have been incarnated as the Apostle Paul of Tarsus and the Neo-Platonic philosopher Iamblichus.Some have believed that he was the Christian saint Hilarion.This is possible, since although the years Iamblichus, also known as Iamblichus Chalcidensis, (c. 245 – c. 325) was embodied overlap the lifetime of St. Hilarion (291–371), various traditions such as Hindu and Tibetan Buddhism hold that it is possible for the spiritually advanced to have more than one incarnation happening at the same time.
