Those who eat the remnants of the sacrifice, which are like nectar, go to the eternal Brahman. This world is not for the man who does not perform sacrifice; how then can he have the other, O Arjuna?

Those who eat the nectar left over from sacrifice reach the eternal Brahman. This world is not for one who offers no sacrifice, best of the Kurus; how then the other?

Krishna returns to the image of the remainder of sacrifice, met earlier in the third chapter. Those who live on what is left after offering, here called amṛta, nectar of immortality, reach the eternal Brahman. One who makes no sacrifice at all has no place even in this world, let alone in any higher one. The verse makes sacrifice a condition of a meaningful life both here and hereafter. To live without giving anything of oneself is to cut oneself off from the order that sustains all.
