Thus there arose, among these “New Initiates,” a knowledge embracing everything contained in the old form of Initiation; but the central point of this teaching was the higher knowledge concerning the Mysteries of the coming of the Christ. Such teaching could only filter through into the general life of the world in scanty measure while the human souls of the fourth period were further developing the faculties of intellect and feeling; therefore, while this lasted, the doctrine was in truth secret. Then began the dawn of the new period designated as the fifth. Its essential characteristic lay in the progress made in the evolution of the intellectual faculties, which were then developed to a very high degree, and will unfold still further in the future. This process has been slowly going on from the twelfth and thirteenth centuries, becoming ever more rapid from the sixteenth century up to the present time. Under these influences the evolution of the fifth period became an ever-increasing endeavour to foster the powers of intellect, while, on the contrary, the knowledge by faith of former times, and traditional wisdom, gradually lost its hold over the human soul. On the other hand, however, from the twelfth and thirteenth centuries on, there developed that which may be called an ever increasing flow of cognition born of modern clairvoyant consciousness. This “hidden knowledge” flows even though at first quite imperceptibly, into the human concepts of that period. It is only natural that even up to the present time the purely intellectual forces should have maintained an antagonistic attitude toward this knowledge. But that which must come to pass will do so in spite of all temporary antagonism. That “hidden knowledge” which is taking possession of humanity more and more may be called symbolically, the “wisdom of the Holy Grail.”
