Since the time of Descartes, the brain has been considered the source of thought and feeling, but always some people have refused to accept this view. D H Lawrence expressed this reluctance as follows:
Man is a creature that thinks with his blood: the heart dwelling in a sea of blood that flows through the body always in two inverse tides is where chiefly lies what men call thought.
And to quote Norbert Wiener, one of the originators of cybernetics:
Messages which cause conditional or associative learning are carried by the slow but pervasive influence of the blood stream. The blood carries in it substances which alter nervous action directly or indirectly.
Compare now these ultramodern theories with the view expressed by a Memphite physician over 4,500 years ago.
The seeing of the eyes and the breathing of the nose bring messages to the heart. The seeing of the eyes and the hearing of the ears and the breathing of the nose bring messages to the heart. It is the heart which causes all decisions to be made, but it is the tongue which reports what the heart has thought. Thus is all action, whether simple or complex, carried out. The manipulation of the hands, the movement of the legs and the functioning of every limb. All is in accord with the command which the heart has devised and which has appeared on the tongue. Thus is determined the specific nature of everything.
These few ancient phrases summarise extraordinarily accurately the concept of mind-body relationship and its role in evolution which our contemporary behaviourist biologists are now struggling to formulate.
Egypt symbolised [the] vision of life energies driven by a symphonic celestial tuning in its well-known texts concerning the twelve divisions or hours of the day and night and of the Dwat, commonly called the Netherworld, or the world of transformations, in which transformations are depicted occurring everywhere – in food, flesh, energy, mind and spirit.
The Dwat is the inner region of transformation beneath or within appearances….The introductory text of the Book of What is in the Dwat, which is divided into twelve chapters, corresponding to the twelve hours of the night reads:
This is the knowledge of the powers of the Netherworld. This is the knowledge of their effects, knowledge of their sacred rhythms [or ritual]. To Re [the Solar Deity], carrier of the knowledge of the mysterious power [or unconscious drive], knowledge of what is contained in the hours as well as in their Gods…[concluding]…O Flesh, who belongest to Sky, but who liveth on earth, O Flesh, Glory to thee. Come Re in the form of the Living One, breath through me here in the Netherworld of the Hours…Transverse the field [or region], O Protector of the body. He shines, the great Light-giver Re drives away darkness.
Here we encounter a blending of physiology with cosmology, the transformative living field of the body expanded into a vision of cosmic transformation. Rhythms set forth in galactical space, passing through hereditary levels, are transmuted into rhythms of incarnate life and mind.
