SB 11.26.14
sevato varsa-pugan me
urvasya adharasavam
na trpyaty atma-bhuh kamo
vahnir ahutibhir yatha
Translation:
Even after I had served the so-called nectar of the lips of Urvasi for many years, my lusty desires kept rising again and again within my heart and were never satisfied, just like a fire that can never be extinguished by the oblations of ghee poured into its flames.
