These lectures were delivered in New York in 1921. The purpose was to present the testimony of science as to the relation of matter and of consciousness; to observe the identical manifestation of these relations and of certain basic laws in successively higher states of being, and thus to bring to them a realization of the universality of the evolutionary process and its actuality; and to deal somewhat with the nature of the expanded states of consciousness and the enlarged life toward which all mankind is traveling.

Throughout the whole of this series of books runs a single thread uniting various aspects of life and specialised activities within the Plan for man. This is the thread of consciousness, evolving in man through the efforts of the soul to contact and control its personality equipment; and evolving within the planet as the centre Hierarchy becomes increasingly able to impress the Plan on the minds of men.

"The Secret of Light" by Walter Russell is a profound exploration of the nature of light and its pivotal role in the universe. Russell, a visionary artist and philosopher, presents a comprehensive treatise on the spiritual and scientific significance of light, positing it as the fundamental force behind all creation.

Five volumes have been written under the overall title of A Treatise on the Seven Rays, based on the fact, the nature, the quality and the interrelationship of the seven streams of energy pervading our solar system, our planet and all that lives and moves within its orbit. The two volumes of Esoteric Psychology go extensively into the psychological make-up of a human being as the life, quality and appearance of an incarnating, evolving spiritual entity.

Seven lectures given by Alice Bailey are brought together in this book of seven chapters. The scientific relation of matter and consciousness is discussed as evolution progressively affects the atomic substance of all forms, subjective and objective.

The idea that a small group of dedicated aspirants could work together to help dissipate the heavy enshrouding glamours which oppress humanity and deflect the light of truth, was initially quite a startling one. Spiritual progress has for so long held no meaning for the individual other than his own personal growth, that to consider spiritual experience in direct relation to world conditions is for many a revolutionary idea.

The theme of "initiation" appears in various relationships throughout this series of books. An initiation is an expansion of consciousness - a means of opening the mind and heart to a recognition of what already exists in reality. It is, therefore, a result of the ability to transcend those glamours and illusions which veil the truth and limit the consciousness. As a living process, initiation is experienced by all forms of life, large and small, from the universal to the particular.

From the author of the landmark Secret Teachings of All Ages comes two classic works on the mysterious origins and unique mission of America: The Secret Destiny of America and America’s Assignment with Destiny. Focusing on often-forgotten moments in history, Manley P. Hall proposes that there was a Great Plan put forth 1,000 years before our nation’s founding: Humanistic and mystical organizations wished for the continent to be the location for an experiment in self-government and religious freedom.

Occultism is not magic. It is comparatively easy to learn the trick of spells and the methods of using the subtler, but still material, forces of physical nature; the powers of the animal soul in man are soon awakened; the forces that his love, his hate, his passion, can call into operation are readily developed. But this is Black Magic–Sorcery. For it is the motive, and the motive alone, that makes any exercise of power become black, malignant, or white, beneficent Magic.

"The Universal One" by Walter Russell is an ambitious and comprehensive work that endeavors to blend the realms of science, philosophy, and spirituality into a singular, cohesive theory of the universe.

Helena Petrovna Blavatsky is best known as the cofounder of theosophy, which is essentially a selective conflation of Hindu and Buddhist ideas combined with Blavatsky's idiosyncratic system of cosmology. The Voice of the Silence, first published in 1889, is described by the author as "chosen fragments from the Book of the Golden Precepts, for the daily use of disciples".

The Externalisation of the Hierarchy concerns the emergence of the spiritual kingdom into the world of humanity’s daily living. But this will only happen when our motives and values begin to mirror those of the soul. This book shows the encouragement humanity has received (and is receiving) to choose the right path. But human freewill – such a hotly debated subject – cannot be interfered with, however urgent the danger, or great the opportunity.

Transcendental Magic: Its Doctrine and Ritual by Éliphas Lévi explores magic, the "esoteric science," and its place between science and religion.

In this short work by the noted lecturer and mystic, Manly P. Hall explores the differences between black and white magic, guiding fellow occultists away from those practices which damage the spirit and lead to the loss of the soul. An essential part of any occultist's library.

At the root of human conflict is our fundamental misunderstanding of who we are. The illusion that we are isolated beings, unconnected to the rest of the universe, has led us to view the “outside” world with hostility, and has fueled our misuse of technology and our violent and hostile subjugation of the natural world. To help us understand that the self is in fact the root and ground of the universe, Alan Watts provides us with a much-needed answer to the problem of personal identity, distilling and adapting the Hindu philosophy of Vedanta.

The subject of initiation greatly fascinates thinkers of all schools of thought, and even those who remain skeptical and critical would like to believe that this ultimate attainment is possible. To those who do not believe that such a goal is possible, this book offers, for what it may be worth, a formulation of an interesting hypothesis. To those who anticipate such a consummation of all their endeavors, this book is tendered in the hope that it may prove an inspiration and a help.
