One of the merits of this book is that it shows how much the Hierarchy and other centers of life on the planet depend on an unpredictable and often irresponsible factor - the free will of man. According to the law, even in a moment of danger, the Hierarchy cannot violate his free will and dictate or impose on him a course of action based on its own deeper knowledge and insight. The book shows the work of energies invisible to the world, and also names some of the great Beings who were magnetically attracted to serve the planet at the climax of the evolution of our planetary life. This book helps to understand the true meaning of the interdependence of all forms of life on our planet in terms of Love, Sacrifice and Service of the part to the Whole.
