You find out that what you are is a force …. A force that makes it possible for your body to live, a force that makes it possible for your whole mind to dream.

Without you, without this force, your body would collapse on the floor. Without you, your whole dream just dissolves into nothing. 
What you really are is a force that is Life. If you look into the eyes of someone near you, you will see the self-awareness, the manifestation of Life, shining in his eyes. 

Life is not the body; it is not the mind; it is not the soul. It is a force. Through this force, a newborn baby becomes a child, a teenager, an adult; it reproduces and grows old. When Life leaves the body, the body decomposes and turns to dust.

You are Life passing through your body, passing through your mind, passing through your soul. 

Once you find that out, not with the logic, not with the intellect, but because you can feel that Life— you find out that you are the force that makes the flowers open and close, that makes the hummingbird fly from flower to flower. 
You find out that you are in every tree, you are in every animal, vegetable, and rock. You are that force that moves wind and breathes through your body. 

The whole universe is a living being that is moved by that force, and that is what you are. You are Life.
