Nor is this a matter of theory only, according to the Occult Records, which give the details of the events alluded to in Genesis vi. _et seq._ This knowledge was, in those ancient times and on the continent of Atlantis, given without any rigid conditions as to the moral elevation, purity, and unselfishness of the candidates. Those who were intellectually qualified were taught, just as men are taught ordinary science in modern days. The publicity now so imperiously demanded was then given, with the result that men became giants in knowledge but also giants in evil, till the earth groaned under her oppressors and the cry of a trampled humanity rang through the worlds. Then came the destruction of Atlantis, the whelming of that vast continent beneath the waters of the ocean, some particulars of which are given in the Hebrew Scriptures in the story of the Noachian deluge, and in the Hindu Scriptures of the further East in the story of Vaivasvata Manu. Since that experience of the danger of allowing unpurified hands to grasp the knowledge which is power, the great Teachers have imposed rigid conditions as regards purity, unselfishness, and self-control on all candidates for such instruction. They distinctly refuse to impart knowledge of this kind to any who will not consent to a rigid discipline, intended to eliminate separateness of feeling and interest. They measure the moral strength of the candidate even more than his intellectual development, for the teaching itself will develope the intellect while it puts a strain on the moral nature. Far better that the Great Ones should be assailed by the ignorant for Their supposed selfishness in withholding knowledge, than that They should precipitate the world into another Atlantean catastrophe.
