CC Ādi 4.178
tāṁs tathaiva bhajāmy aham
manuṣyāḥ pārtha sarvaśaḥ
“In whatever way My devotees surrender unto Me, I reward them accordingly. Everyone follows My path in all respects, O son of Pṛthā.”
Kṛṣṇa was never ungrateful to the gopīs, for as He declares to Arjuna in this verse from the Bhagavad-gītā (4.11), He reciprocates with His devotees in proportion to the transcendental loving service they render unto Him. Everyone follows the path that leads toward Him, but there are different degrees of progress on that path, and the Lord is realized in proportion to one’s advancement. The path is one, but the progress in approaching the ultimate goal is different, and therefore the proportion of realization of this goal — namely the absolute Personality of Godhead — is also different. The gopīs attained the highest goal, and Lord Caitanya affirmed that there is no method of worshiping God higher than that followed by the gopīs.
