Ralph Waldo Trine

Unconsciously, we are forming habits every moment of our lives. Some are habits of a desirable nature; some are those of a most undesirable nature. Some, though not so bad in themselves, are exceedingly bad in their cumulative effects, and cause us at times much loss, much pain and anguish. In contrast, the opposites of these habits would bring us much peace and joy, as well as a continually increasing power.

Before "New Age" there was "New Thought," a philosophy that sought God through metaphysics and was very popular in the late 19th and early 20th centuries. This is the book that started it all.
