By "forehead" is meant man's expression. The smiling forehead is the pleasant expression; it depends solely upon man's attitude to life. Life is the same for the saint and for Satan, and if men are different it is because of their outlook on life. The same life is turned by the one into heaven and by the other into hell. There are two attitudes: to one all is wrong, to the other all is right. Our life in the world from morning to evening is full of experiences, good and bad, which can be distinguished according to their degree. And the more we study the mystery of good and bad the more we see that there really is no such thing as good and bad. It is because of our attitude and the conditions that things seem good or bad. It is easy for an ordinary person to say what is good or bad, just or unjust-it is very difficult for a wise man.
