O King Pariksit.

O Maharaja Pariksit, the demigods were related to Visvarupa from his father’s side, and therefore he visibly offered clarified butter in the fire while chanting mantras such as indraya idam svaha (this is meant for King Indr) and idam agnaye (this is for the demigod of fir). He loudly chanted these mantras and offered each of the demigods his proper share.
