The past actions rest in the vast dwelling of brahma, the manner in which brahma’s writing of letters (our fate) is like the ocean. Therefore the entire past is with Brahma, we are eternally sacrificing, for the status of reputation or for our reputation.
What it says in Prabhupada’s Gita about Text 3.15
Regulated activities are prescribed in the vedas, and the vedas are directly manifested from the supreme personality of Godhead. Consquently the all-pervading transcendence is eternally situated in acts of sacrifice.
