...the field wherein the New Group of World Servers works is that of mankind, conditioned and ruled for the past two thousand years by Piscean energy. This is, as you know, the energy which produces mediation and which develops sensitivity in the individual. The work accomplished by and through this energy is so successfully accomplished that it has produced a mediating group of servers; this group acts as an intermediary between the Hierarchy and Humanity, and it has also developed the sensitive response of humanity to contacts, and to such a degree of sensitivity that the response to be accorded to the activities of the New Group of World Servers is very real and cannot be negated.
It should be remembered that the Piscean energy with which the group has to work is opposed to the incoming energies from the Hierarchy and the New Group of World Servers. This is owing to the fact that the energy of this constellation is passing out concurrently with the sixth ray energy, with which it peculiarly "coincided," as it is esoterically called. Hence the present difficulties. The passing out of the influence of Pisces, the slow withdrawal of the sixth ray force, the incoming Aquarian energy, via the Hierarchy (affecting at this time mainly the Hierarchy itself and the mental and astral planes) are conditions to which we must look for the origin of all our present troubles. In this involved situation, you have a planetary demonstration of the significance of inner causes, producing outer effects. (The Rays and Initiations, pp.234-35)
