Srimad Bhagavatam Canto 10, Chapter 82, Text 47

SB 10.82.47

sri-suka uvaca
adhyatma-siksaya gopya
 evam krsnena siksitah
tad-anusmarana-dhvasta-
 jiva-kosas tam adhyagan
 
Translation: 
 
Sukadeva Gosvami said: Having thus been instructed by Krsna in spiritual matters, the gopis were freed of all tinges of false ego because of their incessant meditation upon Him. And with their deepening absorption in Him, they came to understand Him fully.
 
Purport: 
 
Srila Prabhupada renders this passage as follows in Krsna: “The gopis, having been instructed by Krsna in this philosophy of simultaneous oneness and difference, remained always in Krsna consciousness and thus became liberated from all material contamination. The consciousness of the living entity who falsely presents himself as the enjoyer of the material world is called jiva-kosa, which means imprisonment by the false ego. Not only the gopis but anyone who follows these instructions of Krsna becomes immediately freed from the jiva-kosa imprisonment. A person in full Krsna consciousness is always liberated from false egoism; he utilizes everything for Krsna’s service and is not at any time separated from Krsna.”
