We are thus brought face to face with the position that we cannot have one and the same religious teaching even for a single nation, still less for a single civilisation, or for the whole world. If there be but one teaching, a large number of those to whom it is addressed will entirely escape its influence. If it be made suitable for those whose intelligence is limited, whose morality is elementary, whose perceptions are obtuse, so that it may help and train them, and thus enable them to evolve, it will be a religion utterly unsuitable for those men, living in the same nation, forming part of the same civilisation, who have keen and delicate moral perceptions, bright and subtle intelligence, and evolving spirituality. But if, on the other hand, this latter class is to be helped, if intelligence is to be given a philosophy that it can regard as admirable, if delicate moral perceptions are to be still further refined, if the dawning spiritual nature is to be enabled to develope into the perfect day, then the religion will be so spiritual, so intellectual, and so moral, that when it is preached to the former class it will not touch their minds or their hearts, it will be to them a string of meaningless phrases, incapable of arousing their latent intelligence, or of giving them any motive for conduct which will help them to grow into a purer morality.
Looking, then, at these facts concerning religion, considering its object, its means, its origin, the nature and varying needs of the people to whom it is addressed, recognising the evolution of spiritual, intellectual, and moral faculties in man, and the need of each man for such training as is suitable for the stage of evolution at which he has arrived, we are led to the absolute necessity of a varied and graduated religious teaching, such as will meet these different needs and help each man in his own place.
There is yet another reason why esoteric teaching is desirable with respect to a certain class of truths. It is eminently the fact in regard to this class that "knowledge is power." The public promulgation of a philosophy profoundly intellectual, sufficient to train an already highly developed intellect, and to draw the allegiance of a lofty mind, cannot injure any. It can be preached without hesitation, for it does not attract the ignorant, who turn away from it as dry, stiff, and uninteresting. But there are teachings which deal with the constitution of nature, explain recondite laws, and throw light on hidden processes, the knowledge of which gives control over natural energies, and enables its possessor to direct these energies to certain ends, as a chemist deals with the production of chemical compounds. Such knowledge may be very useful to highly developed men, and may much increase their power of serving the race. But if this knowledge were published to the world, it might and would be misused, just as the knowledge of subtle poisons was misused in the Middle Ages by the Borgias and by others. It would pass into the hands of people of strong intellect, but of unregulated desires, men moved by separative instincts, seeking the gain of their separate selves and careless of the common good. They would be attracted by the idea of gaining powers which would raise them above the general level, and place ordinary humanity at their mercy, and would rush to acquire the knowledge which exalts its possessors to a superhuman rank. They would, by its possession, become yet more selfish and confirmed in their separateness, their pride would be nourished and their sense of aloofness intensified, and thus they would inevitably be driven along the road which leads to diabolism, the Left Hand Path, whose goal is isolation and not union. And they would not only themselves suffer in their inner nature, but they would also become a menace to Society, already suffering sufficiently at the hands of men whose intellect is more evolved than their conscience. Hence arises the necessity of withholding certain teachings from those who, morally, are as yet unfitted to receive them; and this necessity presses on every Teacher who is able to impart such knowledge. He desires to give it to those who will use the powers it confers for the general good, for quickening human evolution; but he equally desires to be no party to giving it to those who would use it for their own aggrandisement at the cost of others.
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.
So much of theory we lay down as bearing on the necessity of a hidden side in all religions. When from theory we turn to facts, we naturally ask: Has this hidden side existed in the past, forming a part of the religions of the world? The answer must be an immediate and unhesitating affirmative; every great religion has claimed to possess a hidden teaching, and has declared that it is the repository of theoretical mystic, and further of practical mystic, or occult, knowledge. The mystic explanation of popular teaching was public, and expounded the latter as an allegory, giving to crude and irrational statements and stories a meaning which the intellect could accept. Behind this theoretical mysticism, as it was behind the popular, there existed further the practical mysticism, a hidden spiritual teaching, which was only imparted under definite conditions, conditions known and published, that must be fulfilled by every candidate. S. Clement of Alexandria mentions this division of the Mysteries. After purification, he says, "are the Minor Mysteries, which have some foundation of instruction and of preliminary preparation for what is to come after; and the Great Mysteries, in which nothing remains to be learned of the universe, but only to contemplate and comprehend nature and things."9
This position cannot be controverted as regards the ancient religions. The Mysteries of Egypt were the glory of that ancient land, and the noblest sons of Greece, such as Plato, went to Saïs and to Thebes to be initiated by Egyptian Teachers of Wisdom. The Mithraic Mysteries of the Persians, the Orphic and Bacchic Mysteries and the later Eleusinian semi-Mysteries of the Greeks, the Mysteries of Samothrace, Scythia, Chaldea, are familiar in name, at least, as household words. Even in the extremely diluted form of the Eleusinian Mysteries, their value is most highly praised by the most eminent men of Greece, as Pindar, Sophocles, Isocrates, Plutarch, and Plato. Especially were they regarded as useful with regard to post-mortem existence, as the Initiated learned that which ensured his future happiness. Sopater further alleged that Initiation established a kinship of the soul with the divine Nature, and in the exoteric Hymn to Demeter covert references are made to the holy child, Iacchus, and to his death and resurrection, as dealt with in the Mysteries.10
From Iamblichus, the great theurgist of the third and fourth centuries A.D., much may be learned as to the object of the Mysteries. Theurgy was magic, "the last part of the sacerdotal science,"11 and was practised in the Greater Mysteries, to evoke the appearance of superior Beings. The theory on which these Mysteries were based may be very briefly thus stated: There is One, prior to all beings, immovable, abiding in the solitude of His own unity. From That arises the Supreme God, the Self-begotten, the
