What’s the problem of this world? The whole problem, you take it: there is no joy. Simple as that, there’s no joy. If they had joy, they would not have done all these nonsensical things, there’s no joy! When you have joy you don’t want to fight, you don’t want to do anything that is harmful, you don’t want to say anything harsh to anyone. Not only that, but you do not want to have something that will spoil this Mother Earth or which will bring ecological problem.
