You are aware that the blood as it flows through the arteries and spreads out in the body is the expression of man's ego and that it becomes a stronger and stronger expression as the ego itself finds its centre, finds its inner centre of strength in an increasing degree. Man's ego will only in a far distant future obtain control of other enclosed portions of the organism. Many other beings are still contained to-day in these other constituents of the human body. Let us call to mind, for example, the three bodily humors, the three juices, chyle, lymph, blood, in order to study them more closely. You perhaps know the significance that these three kinds of fluid have for man. You know that when food is taken in, it is first conveyed through the preparatory organs into the stomach, mixed and prepared with the right juices secreted by the glands so that it can be worked upon through the intestines. There the food is brought into a pulpy condition, the chyme, which is conveyed forwards through the intestines. Whatever can form nutritious material for man is then passed into the body through minute vascular organs called the ‘villi’ in order to serve as nutritive juices for renewing the body. This is one of the substances which we have in the body and which we call the ‘chyle.’
