"The Brotherhood of great seers and sages, united in a common purpose and governed by common ideals and esoteric knowledge, has existed as an association of high adepts under the direct inspiration and guidance of their hierarch, or mahaguru, for many millions of years — certainly for not less than twelve million; in other words, since the appearance on earth of the root-race which preceded our own present fifth root-race...The cause of the disappearance of the Mysteries has always been degeneracy, faithlessness on the part of the students, and their lack of an imperative and heart-reaching call for light. Where there is a genuine spiritual and intellectual call issuing from both heart and mind, there invariably comes the response by way of a new installment of teaching from the Brotherhood. Ch.22"
