2. Human Duality

When we begin to visualise all this it is important, as a basis for an occult method of study, that we also add the fact that what we may call a subsidiary stream branches out from the aorta very near the heart; that this subsidiary stream leads to the brain, thus providing for the upper organs, and from there leads back again in the form of stale blood into the right auricle; and that it is there transformed, as blood which has passed through the brain, so to speak, in the same way as that blood is transformed which comes from the remaining members of the organism. Thus we have a smaller, subsidiary circuit of the blood, in which the brain is inserted, separate from the other main circuit which provides for the entire remaining organism. Now, it is of extraordinary importance for us to bear this fact in mind. For we can only arrive at an important conception, affording us a basis for everything that will enable us to ascend to occult heights, if at this point we first ask ourselves the following question: In the same way in which the upper organs are inserted in the smaller circuit, is there something similar inserted within the circuit of the blood which provides for the rest of the organism. Here we come, as a matter of fact, to a conclusion which even the external, superficial method of study can supply, that is, that there is inserted in the large circuit of the blood the organ we call the spleen; that further on is inserted the liver; and, still further on, the organ which contains the gall prepared by the liver.
