As far as the gopis of Vrndavana were concerned, from the very beginning of their lives they did not know anything beyond Krsna. Krsna and Balarama were their life and soul. The gopis were so attached to Krsna that they could not tolerate not seeing Him even momentarily when their eyelids blinked and impeded their vision. They condemned Brahma, the creator of the body, because he foolishly made eyelids which blinked and checked their seeing Krsna.

From Srila Prabhupada’s Krsna Book, ch. 82: Lord Krsna and Balarama Meet the Inhabitants of Vrndavana
