This book is the natural extension of Schopenhauer's philosophy. The whole of existence has been created for a moral purpose. There is no creator outside the world; the creator and created are one and performing the Divine Comedy in everyday life. The theory of the will's harmonic motion is so simple, logical, accessible, scientific, and self-evident that nobody could have any doubt about its truth. It explains the deepest secrets of the monolithic religions, which nobody has ever been able to see because it is so simple. Simplicity is the seal of the truth, and this book reveals it. Schopenhauer came very close to it, and at the end of his life, he declared it to be "the most difficult of all problems." He hoped that "perhaps someone after me will shed some light in this abyss." This book solves the ultimate mystery of existence and sheds some light in this abyss.
