Unless a genuinely scientific and metaphysical basis is found, it will be discovered, as one famous healing cult has already discovered, that although cures are effected which cannot be doubted, many of these cures are not permanent. The principle which is the key to such healing--if it is to be real healing and not a temporary suppression of symptoms--and which overrides all others, was pointed out in an earlier book (The Inner Reality, also published as Discover Yourself). It is the surrender of the conscious will, the personal will, to a higher power. It is the giving up of ego by offering of your body-problem to the power behind all bodies. The cure is not effected and cannot be effected by the patient himself or by any professional healer who may be employed. It is done only by the Overself itself, which means that it is essentially a bestowal of grace. Now grace is an active force, not a mere intellectual thought or emotional attitude. It is the cosmic willpower, or what Indians call kundalini. This bestowal in turn requires that not merely the body alone be touched, but also the mind. Hence a cure which is genuine and permanent will always involve to some extent a mental re-adjustment, a correction of outlook, even an ethical conversion.
