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. It does not mean that one has to acquire the energy of an elephant or one has to become very learned or intelligent man, simply one has to become sincere and employ whatever energy he has in his possession in the service of the Lord. That is the secret of success in Krishna Consciousness.
