Second, the greater part of the possible explanation is only revealed to initiates who have passed the third Initiation, and even to them in a carefully guarded manner.

Third, the revelation of the close connection between mind and fohat or energy, or between thought power and electrical phenomena - the effect of fohatic impulse on matter - is fraught with peril, and the missing link (if so it might be termed) in the chain of reasoning from phenomena to its initiatory impulse, can only be safely imparted when the bridge between higher and lower mind, is adequately constructed. When the lower is under the control of the higher, or when the quaternary is merging into the triad, then man can be trusted with the [260] remaining four fundamentals. Three of these fundamentals are laid down for us in the Proem of the Secret Doctrine, (S. D., I, 42-44.) and with the evolving concept of psychology, make the revealed three and the dawning fourth. The other three are esoteric and must remain so until each man has for himself worked at his spiritual development, built the bridge between the higher and the lower mind, prepared the shrine in the temple of Solomon for the Light of God, and turned his activities into altruistic helping of the evolutionary plans of the Logos.

Man, in essential essence, is the higher triad demonstrating through a gradually evolving form, the egoic or causal body, and utilizing the lower threefold personality [261] as a means to contact the lower three planes. All this has for purpose the development of perfect self-consciousness. Above the triad stands the Monad or the Father in Heaven - a point of abstraction to man as he views the subject from the physical plane. The Monad stands to him in the position of the Absolute, in the same sense as the undifferentiated Logos stands to the threefold Trinity, to the three Persons of logoic manifestation. The parallel is exact.

1. The Monad.
2. The threefold Triad, Atma-Buddhi-Manas, or spiritual will, intuition, and higher mind.
3. The body egoic or the causal body, the shrine for the buddhic principle. This body is to be built by the power of the mind. It is the manifestation of the three.
4. The threefold lower nature, the points of densest objectivity.
5. This threefold lower nature is in essence a quaternary - the etheric vehicle, animating life or prana, kama-manas, and lower mind. Manas or the fifth principle, forms the link between the lower and the higher. (S. D., I, 107.)

We have, therefore, our lower four, our higher three, and the relation between them, the principle of mind. Here we have the seven formed by the union of the three and the four, and another factor, making eight. The ultimate seven will be seen when buddhi and manas are merged. Much has been hinted at in certain of our occult books about the eighth sphere. I would suggest that in this linking factor of intelligent mind, we have a clue to the mystery. When mind becomes unduly developed and ceases to unite the higher and the lower, it forms a sphere of its own. This is the greatest disaster that can overtake the human unit. [262]
