(16) The three degrees of the ancient Mysteries were, with few exceptions, given in chambers which represented the three great centers of the human and Universal bodies. If possible, the temple itself was constructed in the form of the human body. The candidate entered between the feet and received the highest degree in the point corresponding to the brain. Thus the first degree was the material mystery and its symbol was the generative system; it raised the candidate through the various degrees of concrete thought. The second degree was given in the chamber corresponding to the heart, but represented the middle power which was the mental link. Here the candidate was initiated into the mysteries of abstract thought and lifted as high as the mind was capable of penetrating. He then passed into the third chamber, which, analogous to the brain, occupied the highest position in the temple but, analogous to the heart, was of the greatest dignity. In the brain chamber the heart mystery was given. Here the initiate for the first time truly comprehended the meaning of those immortal words: "As a man thinketh in his heart, so is he." As there are seven hearts in the brain so there are seven brains in the heart, but this is a matter of superphysics of which little can be said at the present time.
