He is a Guru consisting of all Gods - Brahma, Vishnu & Mahesh. The myth of Dattatreyas birth is interesting. Rishi Atri’s wife, Anasuya, because of her devotion to God posed a challenge to Laxmi, Parvati & Saraswati. They asked their husbands to trick her and discredit her. The Gods went as young mendicants and asked Anasuya to serve them food in the nude. She soon realized who they were and with her yogic powers she turned them into babies. Then she fed them in the nude and rocked them in the cradle. The three Goddesses asked for forgiveness and requested Anasuya to return the babies, that is their husbands. In the end, the gods bestowed on her Dattatreya as her child and returned to heaven with their consorts.
