Those who have surrendered to the material nature, he has to suffer. There is no way out. You have accepted this body. You must suffer. Klesada asa dehah. This material body means suffering. So they do not know this. They are making so many arrangements and plans how to become happy, how to become peaceful without any miserable condition, but the rascals, they do not know that so long you have got this material body - either a king's body or an ant's body - you must have to suffer.
