The Seven Principles of the Human Constitution
In regard to man’s mortal and immortal life, we have placed these seven principles into two groups – one containing the three higher principles and therefore called the Triad, the other containing the four lower, and therefore called the Quaternary. The Triad is the deathless part of man’s nature, the “spirit” and soul of Christian terminology; the Quaternary is the mortal part, the “body”, of Christianity.

The following is a brief outline of these Seven Principles, providing only a small segment of a large body of knowledge. We would suggest a thorough study of these principles in order to fully understand their meaning.

Excerpt from “Light of the Soul”, by Alice Bailey
The following seven modifications of mind, produced through the experience of the man upon the Wheel of Life is to bring him to the point where he feels that physical plane living, sentiency and mental processes have nothing to give and utterly fail to satisfy him.  These modifications provide a foundation for understanding the seven states of mind found in this series on Soul-infusion and group consciousness. 

The goal of evolution is to master life, to become people who know who we are and where we are going. Such people know exactly what they are doing. They see clearly, understanding themselves and the conditions around them. Filled with compassion for less progressed beings, they help others learn who they are in the deepest meaning of these words. Such people help others find, as they themselves have found, their true spiritual identity. For all that, one can only point the way to others since all must find the way and become the way for themselves. There are seven stages or “rounds” of human unfoldment which correspond to the development of the seven sheaths:

The following seven states of mind, produced through the experience of the man upon the Wheel of Life is to bring him to the point where he feels that physical plane living, sentiency and mental processes have nothing to give and utterly fail to satisfy him.  He reaches the stage which Paul refers to when he says, "I count all things but loss that I may win Christ."

Humanity has witnessed several approaches to the understanding of the Seven Rays influencing the evolutionary process on our planet. With each shift, in the cycles, impacting our solar system, humanity enters a new sphere of activity that strengthens their interaction with Shamballa and the Hierarchy. As humanity moves into an expanded state of consciousness, the field of perception begins to shift. The constructs which supported and guided us in the past have transformed and are now taking on and exhibiting a fresh dynamic mantle of light.
