1. The transmitter of energy on the physical plane forms the throat center in the body of Brahma, the third aspect.
2. The transmitter of energy upon the astral plane forms the heart center of Brahma.
3. The transmitter of the Word on the mental plane forms the head center of this, the third aspect.

   These three Raja Lords, devas, or transmitters, form the three centers of logoic force in the three worlds. They are the lowest energy aspect of Brahma. [922]

4. The Transmitter of the Word upon the buddhic plane forms the throat center of Vishnu, the second aspect. From thence the Word goes forth that builds the dense physical form of a Heavenly Man or of a solar Logos.
5. The Transmitter of energy upon the monadic plane forms the heart center of Vishnu, the second aspect.
6. The Transmitter of force upon the atmic plane forms the head center of Vishnu.

The above sevenfold tabulation can be, under the law of correspondences, applied equally to every plane, for the transmitters and workers on each plane form similar groups. Equally well can man consider this tabulation in connection with his seven centers, and from a study [923] of the two together he will gain knowledge as to the type of energy which flows through any particular center. These transmitters likewise can be heard sounding forth the Word with particular force and power in that planetary scheme which corresponds to their note and is keyed to their vibration. The planetary schemes, therefore, will fall into a similar grouping, and this will open up for students a vast field of conjecture. The seven Prajapatis fall into two groups of three, with one dominating. Students will do well to remember in studying the solar system, the planes, the schemes, man and the atom, that the groupings of the lines or streams of energy during the evolutionary cycles fall naturally into four divisions:

1. 1-3-3
2. 4-3
3. 3-4
4. 3-1-3

• Division 1 can be understood under the law of correspondences when the nature of the atomic plane of the solar system, the three cosmic etheric planes, and the three planes of human endeavor are investigated in connection with each other.
• Division 2 becomes easier of comprehension when the close relation between the four cosmic etheric planes and the three lower planes is grasped. This can be illuminated by a study of the four physical ethers and the three lower subplanes of our physical plane.
• Division 3 finds the clue to its mystery in the constitution of the mental plane, with its three formless levels, and its four levels of form.
• Division 4 can be grasped as the student arrives at a comprehension of his own nature as a spiritual triad, an egoic body and a threefold lower man. He can likewise approach the first division in a similar manner, and view himself as a primary force or Monad, a triple secondary [924] force or Ego, and a threefold lower energy, or personality, remembering that we are here dealing only with creative energy and with the Brahma aspect of manifestation as it coordinates itself with the Vishnu aspect.
