Lecture II
Each organ of the physical body has behind it this etheric body. Man has an etheric heart, an etheric brain, etc., which holds together the corresponding physical organ. One is naturally tempted to picture the etheric body in a material way, somewhat like a thin cloud, but in reality the etheric body consists of a number of currents of force. The clairvoyant sees in the etheric body of man certain currents that are exceedingly important. Thus, for example, there is a stream which rises from the left foot to the forehead (see diagram), to a point which lies between the eyes, about half an inch down within the brain; it then returns to the other foot; from there it passes to the hand on the opposite side; from thence through the heart into the other hand, and from there back to its starting-point. In this way it forms a pentagram of currents of force.
