Q: What should be the Sadhaka’s attitude with regard to physical illness?
He must first of all remain completely detached in the vital being and in the mind. The illness is the result of the working of the forces of Nature. He must use his will to reject the illness and one’s will must be used as a representative of the Divine Will. When the Divine Will descends into the Adhara then it works no longer indirectly through the Sadhak’s will but directly and removes the illness. When the psychic being awakens then it is able to perceive the influence of the disease even before it enters the body. Not only does one perceive it, but one knows which organ is going to be attacked and one can keep off the attack with the help of the Higher Power.
