SB 10.32.7

aparānimiṣad-dṛgbhyāṁ
 juṣāṇā tan-mukhāmbujam
āpītam api nātṛpyat
 santas tac-caraṇaṁ yathā
Word for word: 
aparā — yet another gopī; animiṣat — unblinking; dṛgbhyām — with eyes; juṣāṇā — relishing; tat — His; mukha-ambujam — lotus face; āpītam — fully tasted; api — although; na atṛpyat — She did not become satiated; santaḥ — mystic saints; tat-caraṇam — His feet; yathā — as.
Translation: 
Another gopī looked with unblinking eyes upon His lotus face, but even after deeply relishing its sweetness She did not feel satiated, just as mystic saints are never satiated when meditating upon the Lord’s feet.
Purport: 

Śrīla Viśvanātha Cakravartī Ṭhākura explains that the analogy given here of saintly persons meditating upon the Lord’s feet is only partially applicable, since the ecstasy the gopīs felt when Kṛṣṇa came back was actually unparalleled. Śrīla Viśvanātha Cakravartī also reveals that this particular gopī is the most fortunate of all, Śrīmatī Rādhārāṇī.
