यज्ञशिष्टामृतभुजो यान्ति ब्रह्म सनातनम्। नायं लोकोऽस्त्ययज्ञस्य कुतो़ऽन्यः कुरुसत्तम।।4.31।।
yajña-śhiṣhṭāmṛita-bhujo yānti brahma sanātanam nāyaṁ loko ’styayajñasya kuto ’nyaḥ kuru-sattama
yajña-śhiṣhṭa amṛita-bhujaḥ—they partake of the nectarean remnants of sacrifice; yānti—go; brahma—the Absolute Truth; sanātanam—eternal; na—never; ayam—this; lokaḥ—planet; asti—is; ayajñasya—for one who performs no sacrifice; kutaḥ—how; anyaḥ—other (world); kuru-sat-tama—best of the Kurus, Arjun
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?
4.31 यज्ञशिष्टामृतभुजः eaters of the nectar -- the remnants of the sacrifice? यान्ति go? ब्रह्म Brahman? सनातनम् eternal? न not? अयम् this? लोकः world? अस्ति is? अयज्ञस्य of the nonsacrificer? कुतः how? अन्यः other? कुरुसत्तम O best of the Kurus.Commentary They go to the eternal Brahman in course of time after attaining the knowledge of the Self through purification of the mind by performing the above
sacrifices. He who does not perform any of these is not fit even for this miserable world. How then can he hope to get a better world than this (Cf.III.13)
