The book gives detailed explicit directions, from Jesus Christ in A Course In Miracles, as to how miracle healing is accomplished.
As Jesus Christ states very early in A Course In Miracles, "Our emphasis is now on healing. The miracle is the means, the Atonement is the principle, and healing is the result. To speak of "a miracle of healing" is to combine two orders of reality inappropriately. Healing is not a miracle. The Atonement, or the final miracle, is a remedy and any type of healing is a result. All healing is essentially the release from fear. To undertake this you cannot be fearful yourself. You do not understand healing because of your own fear."
