Bhagavad Gita 4.31

यज्ञशिष्टामृतभुजो यान्ति ब्रह्म सनातनम्।नायं लोकोऽस्त्ययज्ञस्य कुतो़ऽन्यः कुरुसत्तम॥

yajñaśiṣṭāmṛtabhujo yānti brahma sanātanam |nāyaṃ loko'styayajñasya kuto'nyaḥ kurusattama ||

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

Tasting the nectar of immortality, as the reward of sacrifice, they reach the Eternal. This world is not for those who refuse to sacrifice; nor is the other world.

Our plain-language meaning of this verse is waiting for scholar review.
