It is not difficult to understand why this book has been read by perhaps, tens of millions of people in many languages. The idea has its beginning from the scripture in the Old Testament of the Holy Bible Proverbs chapter 23:7 "For as a man thinketh in his heart so is he". From its source we can see that the message has universal application. All men and women would be better off if they cultivated high minded thoughts and thus went forth to do high minded acts. I consider the Holy Scriptures as the most important books I ever read in my lifetime. I consider the book "Jesus the Christ" by James E Talmage as next most important book I ever read. I consider As a Man Thinketh" to be the next most impotant books I ever read in my lifetime.
