“We can understand, they say, the necessity for concealing from the herd such secrets as the Vril, or the rock-destroying force, discovered by J. W. Keely, of Philadelphia, but we cannot understand how any danger could arise from the revelation of such a purely philosophical doctrine, for instance, as the evolution of the Planetary Chains. The danger was that such doctrines as the Planetary Chain, or the seven Races, at once give a clue to the seven-fold nature of man, for each principle is correlated to a plane, a planet, and a race, and the human principles are, on every plane, correlated to seven-fold occult forces, those of the higher planes being of tremendous power. So that any septenary division at once gives a clue to tremendous occult powers, the abuse of which would cause incalculable evil to humanity; a clue which is, perhaps, no clue to the present generation—especially to Westerns, protected as they are by their very blindness and ignorant materialistic disbelief in the occult—but a clue which would, nevertheless, have been very real in the early centuries of the Christian era to people fully convinced of the reality of Occultism, and entering a cycle of degradation which made them rife for abuse of occult powers and sorcery of the worst description.”
