The richer you are, the more worries you have - problems of security, future. Whatsoever you have, you have to hold it. You have to hold it against others because they are constantly watching for a right opportunity to take it back. Whatsoever you hold, you hold out of violence. And of course, if you have been violent then others can be violent to you. They are just waiting for the right moment. The richer you get, the more worries, more problems, more fears you have. Who bothers, if one is happy?
