Chapter IV: Man and the Evolution of the World

For one acquainted with spiritual science, the insight arrived at in this way by external observation is intensified by something else. It might well be argues that the physical falls a pretty to disease. Now spiritual science is able to show that a large proportions of illnesses are due to some fault or failing in the astral body being transmitted to the etheric, and, through the latter, disturbing the harmony of the physical body, which in itself is perfect. This deeper connection—which can here be no more than indicated—and with it the essential cause of many a disease, eludes that mode of science which would restrict itself to physical and sense-perceptible facts. More often than not, the connection is as follows. Injury to the astral body is followed by morbid symptoms in the physical, not in the same life in which the injury is done, but in a subsequent life. Consequently the laws that prevail here are significant only for those who are ready to admit the repetition of man's life on Earth. But even if one did not wish to concern oneself with these deeper realms of knowledge, common observation would reveal only too clearly that man gives himself up to cravings and enjoyments which undermine the harmony of the physical body. Now cravings, passions, enjoyment and the like have their seat not in the physical but in the astral body. In effect, the latter is in many respects still so imperfect that it can actually mar the perfection of the physical body.
