To balance the solar plexus wakes the great plexus of the breast. In our era this plexus is the great planet of our psychic universe. In the previous sympathetic era the flower of the universal blossomed in the navel. But since Egypt the sun of creative activity beams from the breast, the heart of the supreme Man. This is to us the source of light—the loving heart, the Sacred Heart. Against this we contrast the devouring darkness of the lower man, the devouring whirlpool beneath the navel. Even theosophists don’t realize that the universal lotus really blossoms in the abdomen—that our lower man, our dark, devouring whirlpool, was once the creative source, in human estimation. But in calling the heart the sun, the source of light, we are biologically correct even. For the roots of vision are in the cardiac plexus. But if we were to consider the heart itself, not its great nerve plexus, we should have to go further than the nervous system. If we had to consider the whole lambent blood-stream, we should have to descend too deep for our unpractised minds. Suffice it here to hint that the solar plexus is the first and main clue to the great alimentary-sexual activity in man, an activity at once functional and creatively emotional, whilst the cardiac plexus is first and main clue to the respiratory system and the active-productive manifestations. The mouth and nostrils are gates to each great center, upper and lower—even the breasts have this duality. Yet the clue to respiration and hand activity and vision is in the breast, while the clue to alimentation and passion and sex is in the lower centers. The duality goes so far and is so profound. And the polarity! The great organs, as well as the lymphatic glands, depend each on its own specific center of the unconscious; each is derived from a specific _dynamic_ conscious-clue, what we might almost call a soul-cell. The inherent unconscious, or soul, is the first nucleus subdivided, and from its own subdivisions produced, from its own still-creative constellated nuclei, the organs, glands, nerve-centers of the human organism. This is our answer to materialism and idealism alike. The _nuclear unconscious_ brought forth organs and consciousness alike. And the great nuclei of the unconscious _still_ lie active in the great living nerve-centers, which nerve centers, from the original solar-plexus to the conclusive brain, form one great chain of dual polarity and amplified consciousness.
