What is the Power of Now?
None other than the power of your presence, your consciousness liberated from thought forms.
So deal with the past on the level of the present. The more attention you give to the past, the more you energize it, and the more likely you are going to make a "self" of it. Don't misunderstand: Attention is essential, but not to the past as past. Give attention to the present; give attention to your behavior, to your reactions, moods, thoughts, emotions, fears, and desires as they occur in the present. There's the past in you. If you can be present enough to watch all those things, not critically or analytically but non judgmentally, then you are dealing with the past and dissolving it through the power of your presence. You cannot find yourself by going into the past. You find yourself by coming into the present.
