The more we struggle for advancing our Krishna Consciousness movement, the more we become advanced on the path. Really, devotional service means that we have to employ our energies for the purpose of Krishna Consciousness, and it does not matter what is the volume of such energy, because different persons have got different type of energies, but the best means is that one has to apply his energy as far as possible, that is the secret of success in Krishna Consciousness.
