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. Although everyone, according to his outlook on life, turns things from bad to good and from good to bad, everyone has his own grade of evolution and reasons accordingly.
Sometimes one thing is subtler than others and then it is difficult to judge. There was a time when Wagner's music was not understood, and another time when he was considered the greatest of musicians.
Sometimes things are good, but our own evolution makes them less good for us. What we considered good a few years ago may not seem good at a later degree of evolution. At one time a child appreciates a doll most, later it will prefer the work of great sculptors. This proves that at every step and degree of evolution man's idea of good and bad changes. Therefore a thinker will understand that there is no such thing as right or wrong. If there is wrong, all is wrong; if there is right, all is right.
