The Satvata Tantra Part 2 Verse 8 mentions:
Seeing Kardama Muni's austerities aimed at attaining mystic powers, the Lord appeared as Sukla in a pure and transcendental form. After giving him the benediction that he would appear as his son, with a tear of bliss the Lord created a holy lake.
I know that the son of Kardama Muni was Kapila who is an incarnation of Lord Vishnu but I want to know who the Shukla avatar was?
