In the morning, when you open your window or leave your house, you see the sky and the sun. Try to look at them as if for the first time, and you will discover an entire, subtle life that until now has escaped your notice, because you have allowed an opaque screen to come between you and reality. Only by ridding yourself of this screen will you have a true understanding of things.
True understanding is like a spring, always refreshed, always renewed and enchanted. True knowledge is always full of wonder. You must not be content to cultivate this attitude towards nature alone, but towards human beings as well, for not only will you make unimagined discoveries, but you will become far more attractive and interesting to others.
