śloka 31
yajñaśiṣṭāmṛtabhujo yānti brahma sanātanam |
nāyaṃ loko'styayajñasya kuto'nyaḥ kurusattama ||4-31||
Translation
O best of the Kurus! Those who partake of the nectar that remains after sacrifice attain the eternal Brahman. The man without sacrifice does not even gain this world; how then shall he gain the world beyond?
