The size of the capstone of the Great Pyramid cannot be accurately determined, for, while most investigators have assumed that it was once in place, no vestige of it now remains. There is a curious tendency among the builders of great religious edifices to leave their creations unfinished, thereby signifying that God alone is complete. The capstone--if it existed--was itself a miniature pyramid, the apex of which again would be capped by a smaller block of similar shape, and so on ad infinitum. The capstone therefore is the epitome of the entire structure. Thus, the Pyramid may be likened to the universe and the capstone to man. Following the chain of analogy, the mind is the capstone of man, the spirit the capstone of the mind, and God--the epitome of the whole--the capstone of the spirit. As a rough and unfinished block, man is taken from the quarry and by the secret culture of the Mysteries gradually transformed into a trued and perfect pyramidal capstone. The temple is complete only when the initiate himself becomes the living apex through which the divine power is focused into the diverging structure below.
