A Course in Miracles Topic- Body

The body is a thought made manifest, and thus does not do anything on its own, only doing what mind tells it. 

Freedom must be impossible as long as you perceive a body as yourself. The body is a limit. Who would seek for freedom in a body looks for it where it can not be found. The mind can be made free when it no longer sees itself as in a body, firmly tied to it and sheltered by its presence.                    W-199.1:1-4. (Lesson #19- "I am not a body I am free.")

The body is the ego's home by its own election.  It is the only identification with which the ego feels safe, since the body's vulnerability is its own best argument that you cannot be of God.      T-4.V.4:1,2.  (see also: WB Lesson 201: “I am not a body. I am free. For I am still as God created me.”) 

The body is merely part of your experience in the physical world. Its abilities can be and frequently are over evaluated.   T-2.IV.3:8,9.

 The body is endangered by the mind that hurts itself. The body suffers just in order that the mind will fail to see it is the victim of itself. The body's suffering is a mask the mind holds up to hide what really suffers.      W-76.5.

Learning must lead beyond the body to the re-establishment of the power of the mind in it.                     T-8.VII.12:6.
