What does it really mean by “I am not a body, I am free. I am still as God created me” from ACIM? God is One Quality and this One Quality is Light, which is Love. Light is the container, substance, or body of God and beyond which, nothing can ever be. All is manifested by the Love of God.
I am this One Quality; I am the One Substance of God. I am not the quantified conglomerate of light corpuscles arranged by the gravity of my desires, but the Quality of them that is God. I am not the appearance of my desires, but the Essence of all Desire. Conglomerates of form are mine to mold as I wish for eternity.
In the state in the fire when I was totally disconnected from the senses and perception never was, I knew only this One Quality I Am. All thought conglomerates dissolved back into this Quality and then reappeared the instant they were brought to Mind. The Quality of Light is not seen and unseen as appearance or disappearance, but Known as eternally stable, as a priori to appearance. And this Quality is nothing but the Essence of Love; only Love is concentrated into form and radiated back to Formless. I am not a body, I am Essence; I concentrate and dissolve form at my will. I am free to develop and use my body as I wish forever. I am free to Be Still, as I Am, Formless, and in-form. By the Knowledge that I am not the form but the benefactor of it to satisfy Desire, I am free.
