During his career as an inspirational lecturer and bestselling author, Og Mandino made many friends around the world. One of the most cherished, who always held a special place in Og's heart, is Simon Potter, "ragpicker" and salvager of human lives - whom readers first learned to love in Og's book The Greatest Miracle in the World. In The Greatest Mystery in the World, we once again meet this wise and humble man, whose last residence was a cabin in New England, and become the heirs of his secret treasure. For Simon, when he departs from life, leaves Og a precious legacy: the distilled wisdom of his unique collection of the greatest books about self-motivation and success - books he called "hand of God" books because they seemed to have been written with God's hand guiding the author's. In this new book, Og shares with his millions of readers his old friend's bequest. It is nothing less than a blueprint for success, telling us in plain language exactly what we must do to mount the seven rungs of life's ladder - from material achievement and worldly success to the highest spiritual development. Whatever your most cherished dream may be, Og and his good angel, Simon, with some help from a great blue heron called Franklin, will show you the way to bring it within reach.
