स आवृणोत्यमृतं संप्रयच्छंस्तस्मै न द्रुह्येत्कृतमस्य जानन् ।
In plain words
He takes you in and hands you deathlessness itself, holding nothing back. Never turn on such a man — keep in mind what he has done for you.
Close to the Sanskrit
He shelters [the disciple], bestowing the deathless in full; toward him one should not act with malice, knowing what has been done by him.
