"You may believe that you are responsible for what you do, but not for what you think. The truth is that you are responsible for what you think, because it is only at this level that you can exercise choice. What you do comes from what you think."
In any moment of decision, the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing.
The world is a great mirror. It reflects back to you what you are. If you are loving, if you are friendly, if you are helpful, the world will prove loving and friendly and helpful to you. The world is what you are.
