Wisdom

First of all we shall study the seven-fold nature of man according to the Masonic teaching. We shall consider the whole nature of man as he confronts us; we shall learn to understand the nature of the physical body, which everyone thinks he knows all about but in reality knows nothing. As little as we can see the oxygen in water but must separate it from the hydrogen in order to recognise it, as little do we see the real physical human being when we look at another man standing before us. Man is a combination of physical body, etheric body, astral body and the other higher members of his being, as water is a combination of oxygen and hydrogen. The being who stands before us is the sum total of all these members! If we are to see the physical body alone, the astral body must have separated from it: this is the condition in dreamless sleep. Sleep is a kind of higher chemical separation of the astral body with the higher members of man's nature, from the etheric and physical bodies. But even then it cannot be said that we have the real physical body before us. The physical body is alone only at death, when the etheric body too has left it.
This has a direct and concrete bearing. I will make it clear to you by means of an example. Think of some particular part of the astral body. In the remote past, the pictures which the human being perceived in dim, shadowy clairvoyance, worked very differently than do mental images today. These pictures were impressed, first of all, into the astral body. Let us suppose that at one time pictures of the three dimensions of space — length, breadth, and depth — were impressed into the astral body. This picture of three-dimensional space which was once impressed into the astral body through the old, dim clairvoyance was carried over into the etheric body. Just as a seal is pressed into liquid sealing wax, so did the astral picture impress itself into the etheric body and this in turn moulded the forms of the physical body. Thus the picture of three-dimensional space built an organ in a particular area of the physical body. Originally there was a picture in the astral body of the three perpendicular directions of space; this picture impressed itself, like a seal into wax, into the etheric body and a certain part of the etheric body moulded an organ in the interior of the human ear, namely, the three semi-circular canals. You all have them within you; if they are in any way impaired you cannot orientate yourself within the three directions of space; you get giddy and cannot stand upright. Thus are the pictures of the astral body connected with the forces of the etheric body and the organs of the physical body.
The whole physical body of man in its plastic forms is nothing else than a product of the pictures of the astral body and the forces of the etheric body. Hence those who have no knowledge of the astral and etheric bodies cannot understand the physical body. The astral body is the predecessor of the etheric body and the etheric body is the predecessor of the physical body. Thus the matter is complicated. The three semi-circular canals are a physical organ, just as is the nose. All noses differ from one another although there may be resemblance between the noses of parents and children. If you were able to study the three semicircular canals in the ears of human beings, you would find difference and resemblance just as in the case of noses, for these canals may resemble those of the mother or father. What is not inherited is the innermost spiritual core of being, the Eternal in man which passes through the successive incarnations. Individual talents and faculties are not determined by the brain. Logic is the same in mathematics, in philosophy, or in practical life. The difference in the quality of the faculties becomes apparent only when logic is applied in domains where knowledge depends, for instance, upon the functioning of the semi-circular organs in the ear. Mathematical talent will be particularly marked when these organs are highly developed. An example of this is the Bernoulli family, which produced a succession of fine mathematicians. An individual may possess great incipient talent for music or some other art, but if he is not born into a human body that has inherited the requisite organic structures, he cannot bring these talents to expression.
So you see, the physical world cannot be understood without knowledge of how it is constituted. The Free-Mason does not consider it his task to withdraw in any way from the physical world. Certainly not! For what he has to do is to spiritualise the physical world. He must rise to the highest regions of spiritual life and with the knowledge there obtained labour actively in the physical world, especially in the world of men.
