Here is a quote that gives a clear idea of the subject matter:
“The power of affirmation changes and remolds the putty-like substance that makes up the subconscious areas of the mind. For years we have repeated sayings and statements, attached meaning to them in our thoughts and through listening to ourselves speak. This has helped form our life as we know it today, for the subconscious brings into manifestation the impressions we put into it. Therefore, to change the subconscious pattern and increase its vibration, we must remold with new ideas and new concepts its magnetic forces. This can be done through the power of affirmation.
“An affirmation is a series of positive words repeated time and time again in line with a visual concept. Such a statement can be repeated mentally or, preferably, verbally. If one feels, ‘I can’t,’ he cannot. If he is always criticizing himself and lamenting over what he cannot do, then he has to reverse this pattern and change the flow of magnetic mental force, enliven its intensity by saying orally and feeling through all the pores of his body, ‘I can. I will. I am able to accomplish what I plan.’ “
