The books of Alice A. Bailey, written in cooperation with a Tibetan teacher between 1919-1949, constitute a continuation of the Ageless Wisdom--a body of esoteric teaching handed down from ancient times in a form which is always suitable to each period. Intended to precede and condition the coming era, the Alice A. Bailey writings offer an unparalleled spiritual approach to such subjects as the teaching on Shamballa and the Path of spiritual evolution; the spiritual Hierarchy; the new discipleship and training in meditation as a form of service; the teaching on the seven rays and the new psychology of the soul; the teaching on esoteric astrology; and the new world religion, which emphasizes the common thread of truth linking all the major world faiths. The subject of human free will has always contrived to set men's mental teeth on edge. The fatalist automatically resigns himself to whatever befalls him, seeing in effects no cause attributable to his own action - or inaction; but resigned always to the working of an inexorable fate. The Christian counterpart tends to accept his lot as the working of God's Will in which he has no say or part. At the other extreme stands the rebellious independent, determined to exercise his right to free, self-willed action. This book, as one of its many values, shows the extent to which Hierarchy and other centres of life on the planet are dependent upon the unpredictable and often irresponsible factor of human free will. During the years leading up to the outbreak of World War II, every opportunity and every possible spiritual stimulation was offered to humanity in an effort to avoid precipitation of conflict on to the physical plane. Disciples and aspirants to discipleship were asked to give special cooperation to the Hierarchy, and to make an all-out effort to provide adequate leadership to human thought and decision. All were left free, however, to determine their own limits, if any, and to decide their own actions. According to law, the Hierarchy - even at danger point - could not infringe human free will and dictate or impose a course of action based on their own deeper knowledge and more profound insight. Many of the spiritual factors surrounding the period of human history from 1919 to 1949 are presented in this book. The energies at work behind the world scene are shown; and the identity revealed of certain great Beings magnetically attracted in service towards this planet at a climaxing moment in the evolution of our planetary life. These factors are an aid to our understanding of the interrelated energy patterns within the universe which operate according to law. But essentially they provide the esotericist with knowledge of available energy flow responding to planetary purpose and plan which can be contacted and given conscious and intelligent cooperation, particularly by those in whom the selfish, self-centred will has been transcended so that the spiritual will can be given more adequate expression. Some of these energy factors are particularly clear in the special Messages given over a period of many years at the time of the Festivals of Easter, Wesak and the Christ. Many aspects of Hierarchical work, thought and planning are discussed in these Messages, with the Hierarchical effect shown of planetary evolution and initiation and its reflection into humanity. This achieved a climax at the time of the three Festivals in 1945, when a momentous decision was taken involving, among other results, the eventual externalisation of the Hierarchy and the reappearance of the Christ. The final section of the book discusses the Stages in the Externalisation of the Hierarchy . It is often difficult for the human mind to imagine the problems facing those liberated from the restrictions of form. It is even more difficult to contemplate the effects in those so liberated of a free choice to reassume such a limitation. So we are helped to understand what the interdependence of life on this planet really signifies in terms of love, sacrifice and service by the part to the needs of the whole.
