Do you think that because you are very strong and stout, a big wrestler with muscles, you’ll live? No. For Yamaraja there is no consideration that “Here is a weak person, lean and thin, and here is a very strong person; therefore the strong person should be left over and the lean and thin will be taken to Yamaraja.” No. When the time will come, the lean and thin may be spared, but the strong man may be immediately taken. So this rascaldom, that by exercise… People are very much attached to the body. We have seen everywhere, especially in European, they are very much attached to make the body stout and strong. And in the morning you’ll find… Here also you’ll find. They’re running to make the body str…, as if the strong body will save him from death. This is rascaldom. Therefore pramatta. Crazy. We do not say that you remain very weak and lean and thin. No. You should maintain this body properly, but not that that is my only business, how to maintain this body.
