They will form this next group and they will be concerned with the revelation of the fact of the soul and with the new psychology which will be based upon the seven ray types and the new esoteric astrology. Their major task will be to relate, through approved techniques, the soul and the personality, leading to the revelation of divinity through the medium of humanity. They will act also as transmitters of illumination between groups of thinkers and as illuminators of group thought. They transmit energy from one thought centre to another and, above everything else, they transmit the energy of ideas. The world of ideas is a world of dynamic force centres… These ideas have to be contacted and noted and their energy has to be assimilated and transmitted.
