Atrer apatyam abhikāṅkṣata āha tuṣṭo
Datto mayāham iti yad bhagavān sa dattaḥ
Yogarddhim āpur ubhayīṁ yadu-haihayādyāḥ
Maharishi Atri performed severe austerities seeking the birth of a child. Pleased with his austerities the Supreme Lord appeared before him and said, “I offer myself to you”. Thereafter the Supreme Lord incarnated as the son of Maharishi Atri and became famous as ‘Dattatreya’. Emperor Yadu, Emperor Kartaviryarjuna and others purified themselves by applying the dust from the lotus feet of Lord Datta. With His blessings, not only did they attain the 8 supernatural powers such as Anima etc. while they were living, but they also attained liberation after leaving this body.
