William Walker Atkinson 
Mind Power 
The Secret of Mental Magic

William Walker Atkinson was an influential member of the New Thought movement. He was one of the first people to write about the Law of Attraction. Long before Rhonda Byrne discovered The Secret that one’s positive thoughts are powerful magnets that attract wealth, health, and happiness, Atkinson already knew it. 'I wish to invite you to the consideration of a great principle of Nature-a great natural force that manifests its activities in the phenomena of Dynamic Mentation-a great Something the energies of which I have called 'MIND POWER.’ We shall remove indifference, fear, and doubt, and I Can’t. And replace them with I Can; I Will; I Dare; and I Do!’ -William Walker Atkinson
