Microcosm

Man is a little world -- a microcosm inside the great universe. Like a foetus, he is suspended, by all his three spirits, in the matrix of the macrocosmos; and while his terrestrial body is in constant sympathy with its parent earth, his astral soul lives in unison with the sidereal anima mundi. He is in it, as it is in him, for the world-pervading element fills all space, and is space itself, only shoreless and infinite. As to his third spirit, the divine, what is it but an infinitesimal ray, one of the countless radiations proceeding directly from the Highest Cause -- the Spiritual Light of the World? This is the trinity of organic and inorganic nature -- the spiritual and the physical, which are three in one, and of which Proclus says that "The first monad is the Eternal God; the second, eternity; the third, the paradigm, or pattern of the universe"; the three constituting the Intelligible Triad. Everything in this visible universe is the outflow of this Triad, and a microcosmic triad itself. (HPB, Isis Unveiled II, p. 276)
