viii. The Hyperborean and the Polarean Epoch

With the entering upon the earth, something totally new was added to this. External material processes exercised an effect on the soul, which now appeared in material garb. At first it was only the processes of motion in this material outside world which produced movements within the etheric body. As today we perceive the vibration of the air as sound, these etheric beings perceived the vibrations of the etheric matter which surrounded them. Such a being was basically a single organ of hearing. This sense developed first. But one can see from this that separate organs of hearing developed only later.
