If you simply hear about Krsna but do not repeat what you have heard to others, you will not advance very quickly in your understanding of God. Whatever you hear or read you should explain to others. That is perfection. That is why we have established Back to Godhead magazine. Daily our students hear and read about Krsna, and then they must be thoughtful and write something about the science of Krsna consciousness. And naturally when one writes or speaks of Krsna one must think of Him (dheyah).
