Quote from ACIM Text Chapter 1, Section 6 - Wholeness and Spirit.

The miracle is much like the body in that both are learning aids for facilitating a state in which they become unnecessary. When spirit's original state of direct communication is reached, neither the body nor the miracle serves any purpose. While you believe you are in a body, however, you can choose between loveless and miraculous channels of expression. You can make an empty shell, but you cannot express nothing at all. You can wait, delay, paralyze yourself, or reduce your creativity almost to nothing. But you cannot abolish it. You can destroy your medium of communication, but not your potential. You did not create yourself.
