(13) Since the superior (or spiritual) center is in the midst of the other two, its analogue in the physical body is the heart--the most spiritual and mysterious organ in the human body. The second center (or the link between the superior and inferior worlds) is elevated to the position of greatest physical dignity--the brain. The third (or lower) center is relegated to the position of least physical dignity but greatest physical importance--the generative system. Thus the heart is symbolically the source of life; the brain the link by which, through rational intelligence, life and form are united; and the generative system--or infernal creator--the source of that power by which physical organisms are produced. The ideals and aspirations of the individual depend largely upon which of these three centers of power predominates in scope and activity of expression. In the materialist the lower center is the strongest, in the intellectualist the higher center; but in the initiate the middle center--by bathing the two extremes in a flood of spiritual effulgence--controls wholesomely both the mind and the body.

(35) Behold, thou reasonable Soul, to thee I speak, and not to the Body, thou only apprehendest it:- When the Birth is thus continually generated, then every Form has a Center to the Regeneration; for the whole divine Essence [or Substance] stands in continual and in eternal P Generating (but unchangeably) like the Mind of Man, the Thoughts being continually generated out of the Mind, and the Will and Desiring out of the Thoughts. Out of the Will and Desirousness [is] the Work [generated] which is made a Substance, in the Will, and then the Mouth and Hands, go on to perform what was substantial in the Will.
