Somehow or other we need to fix our mind on favorably serving Krishna. This is the goal of our preaching, our deity worship, and our chanting. It is this favorable absorption in devotion that pleases Krishna most. We can struggle alone with material desires millennium after millennium and be defeated and disappointed birth after birth. We cannot overcome material desires by our own strength. It is essential that we develop the intense desire to somehow or other please Krishna by our activities, and that will require that we focus the mind in devotion.
