During Kali Yuga, Narada advised sages who were performing a yagna (fire ritual) to decide who of the Trimurti (Brahma, Vishnu and Shiva) should receive its fruits.
[1] Vishnu took human form as Srinivasa, left Vaikuntha in search of Lakshmi, reached the Seshachalam Hills in Tirumala, and began meditating.
Lakshmi gave them to the Chola king ruling the Tirumala Hills; the cow would provide milk to Srinivasa daily while it was grazing.
Angered by the cowherd's actions, Srinivasa made the Chola king an asura; sins committed by servants should be born by their employers.
After a few months, Srinivasa and Padmavati went to the seven Tirumala hills to emancipate humankind from the troubles of Kali Yuga.
