the glory of whose birth-rites were beautifully performed
Auspicious in the jātakarman rite — the customary birth ritual is performed for the infant; sages performing it privately know they are celebrating no ordinary child.
delighted by the gopīs' auspicious blessings
Gladdened by the auspicious words of the gopīs — Gokula women sing auspicious songs over the child; their words of blessing fill him with contentment.
who feigned sleep
Who gave the guards a false sleep — the prison guards do not fall into natural sleep; they sleep by the Lord's own Yoga-māyā so that Vasudeva can exit unalarmed.
who pressed and crushed Pūtanā's breast
Kṛṣṇa grasps Pūtanā's poisoned breast and squeezes with such force that her ribcage is crushed; she tries to push him away but cannot break his suckling grip.
