"This is the Book of Spirit, also called the Book of Archetypes. It tells of the twenty one great beings who teach and test you on the way to the highest initiation. As a seeker actually experiences them, some may seem more like impersonal situations than like living beings. But others are definitely real persons. You can learn from them, draw on their strengths and enlist their help. They are part of your own wider self, part of your cosmic inheritance.
The path of initiation is a journey of experience and testing in which spirit becomes the leader of all other parts of ones being. The seeker's mind, emotions, vital energy, and even his or her physical body surrender to the guidance of the soul. To put it another way, the soul gains mastery of earth, air, fire and water and it learns to apply its knowledge according to the light of spirit. This book tells the stages of experience which lead to this victory of spirit. This is why it is named The Book of Spirit."
