Bhakti destroys karma. Why not, since it is a common saying the love conquers hate. Still, why do my karmas remain after so long? It must be that the quality and intensity of my love for God is non-existent! And whose fault is that? The real devotees consist only of love. Uddhava admired the gopis’ love:

Among all persons on earth, these cowherd women alone have actually perfected their embodied lives, for they have achieved the perfection of unalloyed love for Lord Govinda.—Srimad Bhagavatam 10.47.58
