Verse
यज्ञशिष्टामृतभुजो यान्ति ब्रह्म सनातनम् ।नायं लोकोऽस्त्ययज्ञस्य कुतोऽन्यः कुरुसत्तम ॥
O best of the Kurus, they who enjoy the nectar of immortality left over from the sacrifice attain to the eternal Brahman; this world is not for him who doeth not sacrifice, how then any other world?
Gītā 4·31
