Everything that is in action must necessarily work through definite laws. And as the mind is in constant action, alternating its actions at almost every turn of thought or feeling, it is evident that a vast number of laws are employed by the mental process. To know how the mind works, therefore, we must know something about these laws. In the following pages the most important of the mental and metaphysical laws known to date are considered from every possible viewpoint, the principal object being to ascertain their real nature as well as their power and use. In addition, a number of psychological ideas are presented that will throw light both on the inner and the outer workings of the mind. Christian D. Larson was a New Thought leader and teacher, a prolific author of metaphysical and New Thought books. He is credited by Horatio Dresser as being a founder in the New Thought movement. His writings influenced notable New Thought authors and leaders.
