But what is this power which emanates from the brain, and which guides the organizing activity of the soul, but the power of life which is transmitted to the brain from the heart, and which is modified in its activity by the peculiar organization of the latter? Man in his present state does not think with his heart, but with his brain; nevertheless, the heart is superior to the brain, for the brain has been built up by the power which came from the heart; and it is a universal law of nature, that no thing can produce anything superior to itself. During its foetal existence the brain of the child is built up by the blood of the mother; after man is born his brain receives its power of life through the heart, and in spiritually developed man the thought-force created in the brain reacts again upon the will in the heart, controlling its desires and entering into harmonious union with the latter. The ancient alchemists say: "If the Sun (the heart) enters in conjunction with the _Moon_ (the brain) then will Gold (Wisdom) be produced." We see, therefore, in man two centres of life, the heart and the brain, and it may properly be said that the brain is the seat of life, only it may perhaps be added, that it is the secondary seat, while the principal seat is, or ought to be, in the heart. [Dr. H. identifies will with life, yet every one knows that all acts of volition proceed from the brain alone, and never from the heart; hence by his own statement the brain is the seat of life.] According to the doctrines of the Hermetic philosophers, God is the invisible central fire in the universe from which the Light of the Logos (Christ or the celestial Adam) emanated in the beginning. Man being a Microcosm, contains in his heart the image of that internal and invisible central fire of _Love_, which sends the light of thought to the brain and illuminates the mind of the seer. We are at present not living in the age of Love, but in the age of Thought (not the age of _Reason_, but the age of _Reasoning_ and Speculation), and by the law of heredity, life has become pre-eminently concentrated in the brain; while in a more advanced age, when the principle of universal Love and Benevolence will be generally recognized, life will become more strongly concentrated at the heart. Men will then not only think, but feel and become able to recognize the truth by that power which is known to us in its rudimental state as _Intuition_, but which, if developed, will be far superior to that uncertain feeling called Intuition, and become a Sun within the heart, sending its rays far up into the regions of thought. Then, as their Love for the supreme Good increases, will their knowledge increase, and as their knowledge expands will their Will become powerful and free.
