It dawns on the initiate, as he proceeds from one initiation to another, that each time he moves forward on the path, or penetrates into the heart of… - Alice Bailey

It is obvious that in such a series of lectures as this it would be impossible to deal adequately in any way with this stupendous subject, even were I equipped to lecture on such a fundamentally scientific matter. Again, if the conclusions of science were definite upon the evolution of matter, the topic would be, even then, too vast to handle, but they are not, and hence the further complicating of the subject. Therefore I want to preface my remarks to-night by stating that my aim is to speak particularly for those who have no scientific training of any kind, and to give them a general concept of the usually accepted ideas; I seek, then, to make some suggestions which we may find helpful in adjusting our minds to this great problem of matter. Usually when the substance aspect of manifestation has been considered, it has been as a thing apart, and it is only lately that what I might call the "psychology of matter" is beginning to come before the mind of the public through the investigations and conclusions of the broader-minded scientists.

Perhaps we might reverse the idea and state that it is only when third subplane matter of a certain percentage (which percentage is one of the secrets of Initiation) is contained in the vehicles, that the Personality as a conscious whole recognises and obeys that Higher self. After such a percentage is attained, it is then necessary to build in matter of the two higher subplanes on the physical and emotional planes; hence the struggle for the aspirant to purify and discipline the physical body and to subdue the emotional. Purification and subjugation describe the work to be done on the two planes. This involves the use of lower mind, and the three lower vehicles thus become aligned. The vibrations of the abstract levels can then begin to be felt. You need to remember that they come via the causal body, the vehicle of the Higher Self, and the average causal body is on the third subplane of the mental plane. This is a point not sufficiently recognised. Ponder on it. Real abstract thought becomes possible only when the Personality has, by vibration reciprocal to that of the Ego, aligned itself sufficiently to form a fairly unimpeded channel. Then at intervals, rare at first but of increasing frequency, will abstract ideas begin to filter down, to be followed in due time by flashes of real illumination or intuition from the spiritual Triad or the true threefold Ego itself.
