Every man has to be self-asserting, continually guarding his interests in order to live. There are many who toil from morning till evening, guarding their self-interest and thinking about nothing else. And what is it all for? In order to exist. But even germs and grubs exist and enjoy life much better! Birds fly in the air and are quite happy; but man is loading his heart with a thousand troubles, making his responsibilities greater and greater. And in the end he gains nothing; his health is spoiled, his spirit wrecked. He does not know any more where he is, nor where his spirit is; and if he has nothing here he has nothing in the hereafter. Many die without ever having given a thought to the deeper side of life. Not that they did not care for it; but they could not find time for it; they had too much to do in life.
