When you are thinking something, you have the feeling that the thoughts do nothing except inform you the way things are and then you choose to do something and you do it. That's what people generally assume. But actually, the way you think determines the way you're going to do things. Then you don't notice a result comes back, or you don't see it as a result of what you've done, or even less do you see it as a result of how you were thinking. Is that clear?
