The only reason there is a past is because we remember it. The only reason there is a future is because we create it in our minds. In reality, the only thing that exists is the present.
You are aware in the present, not in the past or the future. Most importantly, you are aware that you are aware. It is through this awareness that you gain insight, power and freedom. "I think, therefore I am" becomes "I am aware that I think, therefore I am.”
Awareness is the ultimate power. When you are aware, you are free to choose in this moment.
This is the only moment you can ever have and when you are aware of that, you are powerful.
