Quote from A Course in Miracles Text Chapter 10 - THE IDOLS OF SICKNESS.

T-10.I.4. You will remember everything the instant you desire it wholly, for if to desire wholly is to create, you will have willed away the separation, returning your mind simultaneously to your Creator and your creations. 2 Knowing Them you will have no wish to sleep, but only the desire to waken and be glad. 3 Dreams will be impossible because you will want only truth, and being at last your will, it will be yours.
