A child comes into the world crawling and without teeth, and the old man gets out without teeth and crawling. The extremes are alike, but the one has no experience of the life before him, while the other has gone through it all. When the vibrations of ether are very low, we do not see light, it is darkness; when very high, the result is also darkness. The extremes generally appear to be the same, though one is as distant from the other as the poles. The wall has no desires, so neither has the perfect man. But the wall is not sentient enough to desire, while for the perfect man there is nothing to desire. There are idiots who have no desires in this world, because their brain is imperfect. At the same time, the highest state is when we have no desires, but the two are opposite poles of the same existence. One is near the animal, and the other near to God.
