Ralph Waldo Trine 
In Tune With The Infinite 

Ralph Waldo Trine was an important New Thought writer. In Tune With the Infinite is often cited as the inspiration for Napoleon Hill’s Think and Grow Rich. As with all New Thought writers, Trine’s work helped to shape the current crop of self-help books, such as The Secret, The Power of Positive Thinking, and The Law of Attraction.
