One perspective is that different stages of awareness exist.  If you perceive and experience life in terms of past, present and future, then you can be aware after you have done something, as you are doing something and before you are going to do something.  Reflecting consciously on an experience allows you to be more fully  awake.  You gain insight and understanding. Whenever awareness penetrates deeply, you grow more mindful, foresee possibilities, and recognize you shape what unfolds.  Take responsibility to Transform your Life.
