Awareness means that whatsoever is happening in the moment is happening with complete consciousness; you are present there. If you are present when anger is happening, anger cannot happen. It can happen only when you are fast asleep. When you are present, immediate, transformation starts in your being, because when you are present, aware, many things are simply not possible. All that is called sin is not possible if you are aware. So, in fact, there is only one sin and that is unawareness.
