Awareness is fire.
When Heraclitus says that fire is the root of all existence, he is right. He knows something - fire is the root of all existence. Not the fire that you see; that fire is just one of the forms.
Understanding is like fire: it burns you completely; you as you are right now - the ego, the mind.
It gives you a different dimension: you become a cloud and you move in the sky. You have gained wings.
