Each person is living in a world of his own making, and he should speak only such words and think only such thoughts as he wishes to see manifested in his life. We must not hear, think, speak, read, or listen to limitation of any kind. There is no way under heaven whereby we can think two kinds of thoughts and get only one result; it is impossible, and the sooner we realize it the sooner we shall arrive. -from "How to Attain Strength" New Thought proponents at the turn of the 20th century sought to use mysticism to unleash the forces of the universe in themselves. In this classic Dodd, Mead & Company; New York work, the preeminent metaphysicist of the day-Ernest Holmes, founder of the Institute of Religious Science-shares his spiritual philosophy of positive thinking and his "Law of Mind in Action," which, when used to their full extent, cannot help but bring success and happiness. From his advice on "how to attract friends" to his cautionary explanation of why so many fail, Holmes takes us on what he deems "a delightful spiritual adventure."
