"Suppose a man is wearing a heavy coat on a sunny day. The coat
makes him hot and uncomfortable, but he carelessly forgets to
remove it. This is the human situation. We need only remove our
heavy and useless ideas in order to enjoy fair weather. We never
need to create a sunny day, for if we are sunny, so is the day.
Our own nature, whether pleasant or stormy, is the very psycho-
logical weather we experience."
