BG 3.10-12
Having in ancient times emanated mankind together with sacrifice, the Lord of emanation said: "By this shall ye propagate; be this to you the giver of desire; "With this nourish ye the Shining Ones, and may the Shining Ones nourish you; thus nourishing one another ye shall reap the supremest good. "For, nourished by sacrifice, the Shining Ones shall bestow on you the enjoyments you desire." A thief verily is he who enjoyeth what is given by Them without returning Them aught.
