Again, extend the second statement anent the etheric composition of the bodies of men to Those of the Heavenly Men, and it will be found that just as the majority of human etheric bodies are built of matter of the fourth ether, so it may also be said that four of the Heavenly Men have Their etheric vehicles composed of this fourth cosmic ether (buddhic matter).

As time elapses the work of the Heavenly Men in the cosmic etheric spheres will be better comprehended, and assisted intelligently by those lesser intelligences who - by the study of the physical ethers - will eventually hold the key of the greater manifestation. Science is the handmaiden of wisdom, and opens the door to those infinite reaches and to those cosmic expanses, where stand Those vaster Intelligences, Who manipulate the matter of the higher planes, and bend it to the desired form, causing the vibrations thus set up to be felt at the furthest bounds of the solar ring-pass-not. Automatically then all lesser lives and all the denser materials are swept and carried into the needed channels and forms. Vibration or initial activity, light, or activity taking form and animating form, sound the basis of differentiation and the source of the evolutionary process, and color the sevenfold differentiation - thus is the work carried on. We have been dealing with these four in connection with a solar Logos, and equally with the work of a Heavenly Man and of Man, of, the human monad.
