स य एतदेवममृतं वेद साध्यानामेवै-को भूत्वा ब्रह्मणैव मुखेनैतदेवामृतं दृष्ट्वातृप्यति स एतदेव रूपमभिसंविशत्येतस्माद्रूपादुदेति ॥ ३ ॥
In plain words
Whoever knows this very nectar in this way becomes one with the Sādhyas, and seeing this nectar through the mouth of Brahman alone, finds complete fulfillment. He merges directly into that form, and rises up from it once more.
Close to the Sanskrit
He who thus knows this very nectar, becoming one indeed of the Sādhyas, having seen this very nectar through the mouth of Brahman alone, is satisfied. He enters into this very form, and rises up from this form.
