Two sides

Sadness is a natural and necessary aspect to life. We need not try to run away from it, but we can learn to accept it. And by accepting it, we need not be controlled by it.

There are as many nights as days, and the one is just as long as the other in the year’s course. Even a happy life cannot be without a measure of darkness, and the word ‘happy’ would lose its meaning if it were not balanced by sadness.
Carl Jung
