Perhaps the greatest challenge, once fully awake, is to simply witness our being rather than forcing ourselves to be something different, or better. To drop all reaching and simply open like a clam waiting in the deep until life in all its guises floods through the half-closed centre that is us.
Then light, or spirit, or God can enter us like a brilliant stone falling in a lake. Allowing the past to ripple behind us and the future ripple before us, and in that space we are breathing in eternity.
You are whole. You are complete. You are eternal.
