Here your Blessed-self will find both books, Scientific Healing Affirmations (1925 Edition) and The Psychological Chart (1925 Edition) together, as originally published by Swami Yoganandaji.

Spiritual Power of Man's Word :

Man's word is Spirit in man. Words are sounds occasioned by the vibrations of thoughts. Thoughts are vibrations sent forth by the Ego or Soul. Every word that leaves your mouth ought to be potent with your genuine soul vibration. Words in most people are lifeless because they are automatically put forth into the ether, without being impregnated with soul force. Too much talking, exaggeration or falsehood used in connection with words is just like shooting bullets out of a toy gun, without the gun-powder. That is why the prayers or words of such people do not produce any desired definite change in the order of things. Every word you utter you must mean it, i.e., every word you put forth must represent not only Truth, but some of your realized soul force.

Words without soul force are husks without the corn. Words that are saturated with sincerity, conviction, faith and intuition are just like highly explosive vibration bombs, which when let out, are sure to explode the rocks of difficulties and create the change desired. Avoid speaking unpleasant words, even though they are true. Words must be intoned according to the convictions within. Sincere words or affirmations repeated understandingly, feelingly and willingly are sure to move the Omnipresent Cosmic Vibratory Force and render you aid in your difficulty. Only appeal to that Force with infinite confidence, casting out all doubt and the spirit of looking for the desired result. If you don't do this, your appealing attention is deflected and side-tracked from its objective mark. Besides you cannot sow the vibratory prayer seed in the soil of Cosmic Consciousness and then pick it out every minute to see if it has germinated into the desired result or not.

The God-Given Power of Man :

It should be remembered that there is nothing greater in power than the Cosmic Consciousness or God. The Power of Cosmic Consciousness is greater than the power of your mind or the mind of others. Thus you should seek Its aid alone. But this does not mean that you should make yourself passive, inert or credulous, or that you should minimize the power of your mind. Remember God helps those that help themselves. He gave you will power, concentration, faith, reason and common sense to help yourself in your bodily or mental afflictions. You must use them all as you seek the Divine help.

But remember in using your own will power or common sense to get rid of a difficulty or disease, you must not rely wholly on, or harness yourself solely to, your Ego and thus disconnect yourself from the Divine Force. Always during affirmations or prayer vibrations feel that you are using your own but God - given power to heal yourself or others. Always believe that it is not God only but yourself also who, as His beloved child, tries to employ His given will, reason, etc., to react on the difficult problems of life. A balance must be struck between the old idea of wholly depending on God, and the modern way of sole dependence on the ego.

During the different affirmations, the attitude of the mind should be different, e.g., will affirmations should be accompanied by strong will; feeling affirmations by devotion; reason affirmations by intelligence and devotion; imagination affirmations by firm fancy and faith. In healing others select that affirmation which is suitable to the co native, imaginative, emotional or thoughtful temperament of your patient. In all affirmations the intensity of attention comes first, but continuity and repetition count a great deal, too. Impregnate your affirmations with your devotion, will and faith, intensely and repeatedly, unmindful of the results, which will naturally come as the fruit of your labors.

What Cures? The Life Energy!

Drugs, medicine, massage, spinal adjustment or electrical treatment all help to bring back the lost harmonious condition of the cells by chemicalization of the blood or stimulation of certain tissues. These are external methods that sometimes assist the life-energy to effect a cure. But they have not the power to act on a dead body, whence the life energy has vanished, for there is nothing in a dead man that can utilize the properties of medicine or electrical currents. Without the life energy, medicines, etc., cannot have any healing effect on the human body. Hence it can be seen that it is the life energy alone that can effect a cure; all external methods of stimulation can only co-operate with the life energy, and are powerless without it.
