Vishnu

Vishnu datta is a person who had studied sastras and does all swakarmas in the manner instructed in the sastras. He does Vaiswadevam daily(a karma as per Vedas) and pooja to the guest. While Vishnu datta was waiting for the guest as usual he saw an ugly looking beggar at the door. As per Vedas, one who comes for food is Vishnu. Vishnu data took the food and gave it to the beggar. Seeing the shining in the eyes, Vishudatta had a feeling that this was not a beggar. The beggar went out running and Vishnu datta followed him. The beggar beat Vishnu datta with stones and branches of trees. Vishnu datta however managed to catch hold of the feet of the beggar. Lord Dattathreya in the form of the beggar gave mantropadesa and blessed Vishnu datta.

VIishnu datta  was tested thrice in the form of spirits and as he became victorious he was given a lot of boons and mantropadesas making him elite. Vishnu datta made a lot of people redress their grievences with the powers received from Dattathreya. With the help of Datta mantras, a Brahman boy with hot temper and bad manners was corrected. When somebody does his dharma, Bhagavan gives darsan and moksha.
