Srila Prabhupāda explains in the Upadeśāmṛta that devotional service is a cultivation of desire: we simply have to cultivate the desire to serve Kṛṣṇa, and not our senses. And when we look at our own hearts and see our non-capacity for doing that, we should feel something. We should feel that we need help.
