I have been going through my older files of late, and ran across this fine article posted by Hansadutta Prabhu some years ago on his site Krsna World.
Although Srila Prabhupada wrote many books, he one day asked me, “So why did I write all these books?” I said, “So we can know the philosophy, learn the philosophy.” He said, “No, the purpose of all these books is to convince you to chant the holy name of Krishna.”
The Holy Name Is All There Is

Chanting is exactly like the simple method of inhaling and exhaling. Although it seems like a very simple act, it is nevertheless the essence of the whole thing. Without that inhaling and exhaling, none of the other activities can take place. We also understand that no one simply inhales and exhales, but all the other activities are supportive of the inhaling and exhaling.
