One of the primary characteristics of a devotee is krsnaika-sarana, that he is surrendered to Krishna. Surrender includes seeing everything as both connected to Krishna and meant for His pleasure; a surrendered devotee does not try to enjoy matter him or herself. Therefore, it is said that one who suffers from hrdaya-daurbalyam, weaknesses of heart in executing bhakti, is attached to things that have no direct relationship with Krishna. How can something not have a direct relationship with Krishna? Whenever we see the particular object as meant for our own pleasure. If we are seeing something as meant to please our senses, we will find it impossible to simultaneously see it as meant for Krishna’s pleasure. That includes ourselves. We are meant for Krishna’s pleasure too.
