ChU 3.6.3
स य एतद् एवम् अमृतं वेद वसूनाम् एवैको भूत्वाग्निनैव मुखेनैतद् एवामृतं दृष्ट्वा तृप्यति । स एतद् एव रूपम् अभिसंविशति । एतस्माद् रूपाद् उदेति
sa ya etad evam amṛtaṃ veda vasūnām evaiko bhūtvāgninaiva mukhenaitad evāmṛtaṃ dṛṣṭvā tṛpyati | sa etad eva rūpam abhisaṃviśati | etasmād rūpād udeti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He who thus knows this nectar, becomes one of the Vasus, with Agni at their head, he sees the nectar and rejoices. And he, too, having entered that colour, rises again from that colour.
Translated by F. Max Müller
