Thoughts are forces-like builds like and like attracts like. Thoughts of strength both build strength from within and attract it from without. Thoughts of weakness actualize weakness from within and attract it from without. Courage begets strength, fear begets weakness. And so courage begets success, fear begets failure.Ralph Waldo Trine was a philosopher, mystic, teacher, author and early mentors of the New Thought Movement. As an author Trine has far outsold other New Thought authors.
