There is here a most interesting distinction and one that is seldom grasped. Esoterically speaking, the word "matter" or material is given to all forms in the three worlds; and though the average human being finds it difficult to understand that the medium in which the mental processes take place and that of which all thought-forms are made is matter from the spiritual angle, yet so it is; substance - technically speaking and esoterically understood - is in reality cosmic etheric matter, or that of which the four higher planes of our seven planes are composed. From the human angle, ability to work with and in the cosmic etheric substance demonstrates first of all when the abstract mind awakens and begins to impress the concrete mind; an intuition is an idea clothed in etheric substance, and the moment a man becomes responsive to those ideas, he can begin to master the techniques of etheric control. All this is, in reality, an aspect of the great creative process: ideas, emanating from the buddhic levels of being (the first or lowest cosmic ether) must be clothed in matter of the abstract levels of the mental plane; then they must be clothed in matter of the concrete mental plane; later, with desire matter, and finally (if they live so long) they assume physical form. An idea which comes from the intuitive levels of the divine consciousness is a true idea. It is noted or apprehended by the man who has, within his equipment, substance of the same quality - for it is the magnetic relation between the man and the idea which has made its apprehension possible. In the great creative process he must give form to the idea, if he possibly can, and thus the creative artist or the creative humanitarian comes into being and the divine creative intention is thereby aided.
