The Power of Words [EPUB ebook] 

Man’s word is his wand filled with magic and power!
Jesus Christ emphasized the power of the word; ‘By thy words thou shalt be justified and by thy words thou shalt be condemned, ‘ and ‘death and life are in power of the tongue.’
So man has power to change an unhappy condition by waving over it the wand of his word.
The imaging faculty is the creative faculty and it is important to choose words which bring a flash of the fulfillment of the demand.
Never force a picture by visualizing; let the Divine Idea flash into your conscious mind; then the student is working according to the Divine Design.
