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.

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.

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.

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.

Although this book was one of the first to be written by Alice Bailey in collaboration with the Tibetan, it is probably the most timeless, profound and least understood. "A Treatise on Cosmic Fire" deals with the underlying structure of occult teaching for the present era, with vast cosmic processes reproduced though all areas of life from universe to atom. It is, therefore, no book for the proof-demanding concrete mind, or for those who dabble in the spectacular and the phenomenal.

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.

Thinkers everywhere are conscious of two things, first, that the region of mystery has never before been so clearly defined, and secondly, that that region can be entered more easily than has hitherto been the case; it may, therefore, perhaps be induced to render up some of its secrets if investigators of all schools pursue their search with determination.

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.

Many spiritual traditions encourage us to relinquish our will to the divine and allow love to guide our actions in daily life. But how do we do this? In this unique program, Dr. David Hawkins explains how integrity, spiritual intention, and our willingness to surrender to the Presence of God is the pathway of the heart and to knowing God. He explores various ways to end suffering and guides us in the practice of letting go. Dr. Hawkins offers his unique perspective on what is a spiritual life and gives guidance on how to overcome the obstacles along the way.

"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.
