The cosmic mental plane. This manifests for us in the three types of force to be seen on the systemic mental plane. These three types have not been sufficiently studied, and are:

1. The force which plays through all the manasic permanent atoms, and which produces basically that manifestation which we call the three worlds.
2. The force which animates those groups of "lotuses" [623] which we call egoic groups or centers - aggregations of causal bodies.
3. The force which vitalizes all the mental units and which is distributed thence to all the other permanent atoms.

First. The devas who are the substance or force of the astral plane, viewing it as the sumtotal of desire, of feeling and of sensation. They are, therefore, the nerve centers, or nerve plexi, of the logoic physical body, for the systemic astral plane provides the nervous system of the logoic physical body. It is the body of intensest vibration from the physical standpoint, and the vehicle through which all is transmitted to that portion of the logoic physical body which corresponds to the brain [624] in man. I can elucidate this no further, but the few words here imparted open up a tremendous range of thought, and give the key to much which transpires and which is distressing in solar evolution as well as human.

The Cosmic Physical Plane. This is the force (external and internal) of the solar system itself, and of its environing space. It might be regarded as the pranic forces, pouring through the logoic etheric body (our four higher subplanes) which are positive to the lower three, impregnating these lower three planes (a reflection in substance, or in the Brahma aspect, of the union of Father-Mother) and producing the purely concrete manifestation. This is why the physical vehicle has such control during long stages of man's evolution, for the force of this type of energy is necessarily felt more strongly than any other. It is deva force, and substance, which is so close to us as powerfully to delude us. Here lies the mystery of maya, and here is to be found the secret of illusion. Here exists for man the first great stage of the battle for full Self-consciousness, and for identification with the God-aspect, and not with the [625] matter-aspect. Here lies the occult reason why man is called by his father's name and not his mother's. When man has dominated the deva essences of the physical plane, he controls next those of the astral and dominates the mental essences. Having achieved this in his own nature he can then safely become a magician and contact, control and work with, the devas in connection with the plans of the Heavenly Man. In the realization of the three types of force, will be found for man the key to the mystery of his centers.
