People generally speak, "God is great." That is very good. At least, one accepts God is great. But how He is great and what is the extent of His greatness, if we understand, then our regard and reverence for Krsna increases. Just like we have got some friend, but if we know the opulence of the friend, how great he is... He may be a very big man, very big business magnate or minister. If we know, then our, "Oh, you have got such a nice friend." Similarly, we should try to understand Krsna.
