On Metempsychosis, or Reincarnation
“Indian contact with the Greeks can be traced back to Alexander the Great, establishing trade and exchange between the eastern Mediterranean, the Middle East (Persian), and India. The classic narrative of this relationship is found in the Life of Apollonius of Tyana (recorded by Philostratus, c. 220 CE). Apollonius journeyed to India to study at the sacred hill of the Indian “wise men marked with a crescent on their foreheads”. When Apollonius (d. 98 CE) was asked about why he came on such a long journey, he replied “Your ways are wiser and much more godly”, clearly indicating a classic Greek respect for Indian thought at the time of Roman Philostratus (36).
Another example, far more significant, is that of the teachings of the Persian religious leader, Mani (c. 245 CE). According to Mani’s teachings, the Apostles of Light sent by Jesus to redeem humanity included the Buddha and Manichaeism is distinctively influenced by Buddhist ideas, such as Mani representing himself as the Buddha to come, Maitreya (37). In esoteric circles, Iranian syncretic religions (such as those of Kushan) came to be regarded as influenced by both Greco-Roman and Indo-Iranian ideas, ideas that have carried over into the history of various forms of Western Esotericism but are little studied (38).
One of the significant esoteric teachings contained in the Life of Apollonius, recorded as a teaching of the Indian sages, is that on reincarnation. When Apollonius asks about the nature of the soul, he is told that, like Pythagoras and Plato, human beings live many lives in diverse bodies based on past actions. Further, the Indian sages claim that this teaching which was taught to the Greek philosophers in Egypt was transmitted to the Egyptians by ancient Rishis’ of India who migrated to north Africa (Ethiopia) from the Ganges River basin (39).
The belief in reincarnation or metempsychosis has very ancient roots in India and is the probable source of that belief in the classical period of formative Gnosticism (40). Gnostic teachers such as Basilides propagated the idea along with other groups such as the Carpocratians and Ophites, and it was popular among various Neoplatonists such as Alcinous, as well as taught by the archetypal magician, Simon Magus. It was also taught by Mani as the fate of the “Hearers” who did not attain perfection (41). Gnostic texts such as the Zostrianos, The Treatise on Resurrection, and the later Pistis Sophia further propagated ideas of reincarnation for the “inpenitent soul” that it might try again to attain the goal of liberation from worldly life (42). Thus a very early Indian influence in Western Esotericism may have roots in the spread and popularity of ideas of reincarnation, also found in early elements of Christianity but later repressed.”
