We all make promises to ourselves. In doing so, we make promises to our G.O.D. (what author Julia Cameron calls Good Orderly Direction). This is so because our life is only made possible from of the light and love from the sun, the moon and the stars–all of which, are also made from the order and direction of The One.
Think of each breath as a promise to ourselves, and to our G.O.D., to fully live. If you held your breath, you would be breaking each promise. Think that each time you hold back from living fully, you suffocate and smother your spirit.
Understand that the only promises worth making, are those that can be kept.
