The quality of your action depends on the quality of your being. Suppose you’re eager to offer happiness, to make someone happy. That’s a good thing to do. But if you’re not happy, then you can’t do that. In order to make another person happy, you have to be happy yourself. So there’s a link between doing and being. If you don’t succeed in being, you can’t succeed in doing. If you don’t feel that you’re on the right path, happiness isn’t possible. This is true for everyone; if you don’t know where you’re going, you suffer. It’s very important to realize your path and see your true way.
