In the "Bhagavata Purana" Dattatreya enumerates a list of his twenty-four gurus: earth, air, sky / ether, water, fire, sun, moon, python, pigeons, sea, moth, bee, bull elephant, bear, deer, fish, osprey, a child, a maiden, a courtesan, a blacksmith, serpent, spider, and wasp. The image of the Natha ranged from that of a siddha living in the woods with animals, to that of a frightening, even demonic, being.
