Publisher's Synopsis
Many writers on the subject of the human aura content themselves with a description of the colors of the mental or emotional aura, and omit almost any reference whatsoever to the basic substance or power of the aura. This is like the play of Hamlet, with the character of Hamlet omitted, for, unless we understand something concerning the fundamental substance of which the aura is composed, we cannot expect to arrive at a clear understanding of the phenomena which arises from and by reason of the existence of this fundamental substance. We might as well expect a student to understand the principles of color, without having been made acquainted with the principles of light.
