First in Krishna Consciousness there is a duty, which must be there. There are so many duties – duties to the spiritual master, duties to principles of purity, duties according to the scriptures, duties given to us by the arcaryas. It governs everything – the time we rise and the duty must be there first. If duty is not in place, then there is something hollow, and then there is the vacuum in our spiritual life. When there is such a vacuum, than our bhakti cannot really grow. For sometime, it may look like that bhakti grows very nicely, but if there is a vacuum remaining in our duty, then all that bhakti that emerges so nicely – will at one point just collapse! So the duty must be there!
