Dattatreya
Though the Dattatreya of the Natha tradition coexisted and intermingled with the Puranic, Brahmanical tradition of the Datta sampradaya, here we shall focus almost exclusively on the earlier Tantric manifestation of Datta. Shri Gurudev Mahendranath had no doubt that Dattatreya was a historical figure. He stated that Datta was born on Wednesday, the fourteenth day of the full moon in the month of Margasirsa, though he does not mention the year.
