I always remember you that you are such a sincere and good boy, and I am sure that Lord Krishna will help you more and more to advance in Krishna Consciousness. Krishna is very merciful to His sincere devotees, but also we have to remember that Maya is very strong. Therefore, we have to always be engaged in serving Krishna. At every moment we should be doing this or that service for Krishna’s transcendental pleasure. If we do not remember this, then Maya is right there to grab us. It all depends upon our leaning towards Krishna or towards Maya. If you lean towards Krishna, you will be in Krishna Consciousness; and if you lean towards Maya, then you will be captivated by material nature. Krishna and Maya are just like light and shadow which are directly next to one another. If you move a little this way, you are in light and there is no question of shadow. But if you move a little the other way, you are in darkness. So if we remember to always be engaged in Krishna’s service, then there will be no Maya and everything will be all right. Please always remember this great secret of advancement in Krishna Consciousness.
