This is definitely one of the best prosperity book, if not the best one! Another great books are "Science of Getting Rich" by Wallace D. Wattles and "Spiritual Economics" by Eric Butterworth. Why I think this book as the best amongst them, because I think it pierced through the core of prosperity itself, which is Infinite Spirit and Infinite Substance of All (or God). It's also teach us to transcend the limited way of seeing money and prosperity. To release the acquisitiveness attitude to life and prosperity, and instead to stay centered in our Truth and Infinite Beingness as the very source of supplies and all things in life. I can say I'm really transformed by reading this for the first time. I can see just in a matter of few days that my energy changes. I feel more centered in Spirit and have deeper faith in Infinite Substance. There's also an effortless demonstration of abundance in my daily life. The usual LoA stuff really looks pale in comparison with this book/Charles Fillmore's teaching. While LoA is all about getting, getting, and desire; Fillmore taught us the realization of Spirit and how to own and express that power in our daily life.
