Sickness is a defense against the truth. I will accept the truth of what I am, and let my mind be wholly healed today.
(ACIM, W-136.15:6-7)
I have forgotten what I really am, for I mistook my body for myself. Sickness is a defense against the truth. But I am not a body. And my mind cannot attack. So I can not be sick.
(ACIM, W-136.20:3-7)
