Some Yogis follow the plan of placing both hands on the affected part, and then breathing rhythmically, holding the mental image that they are fairly pumping prana into the diseased organ and part, stimulating it and driving out diseased conditions, as pumping into a pail of dirty water will drive out the latter and fill the bucket with fresh water.

This last plan is very effective if the mental image of the pump is clearly held, the inhalation representing the lifting of the pump handle and the exhalation the actual pumping.
(6) HEALING OTHERS.
We cannot take up the question of the psychic treatment of disease by prana in detail in this book, as such would be foreign to its purpose.
But we can and will give you simple, plain instructions whereby you may be enabled to do much good in relieving others.

The main principle to remember is that by rhythmic breathing and controlled thought you are enabled to absorb a considerable amount of prana, and are also able to pass it into the body of another person, stimulating weakened parts and organs and imparting health and driving out diseased conditions.

You must first learn to form such a clear mental image of the desired condition that you will be able to actually feel the influx of prana, and the force running down your arms and out of your finger tips into the body of the patient.

Breathe rhythmically a few times until the rhythm is fairly established, then place your bands upon the affected part of the body of the patient, letting them rest lightly over the part.
