“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.”

“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. It is far better take things as they come along with patience and equanimity.”

“For a moment, I thought of the word happy and it was a word that just, well, it felt like it was visiting me. I knew it wouldn’t last for very long and I’d be sad again and then it would be worse because it’s one thing to be sad and it’s another thing to be sad once you’ve been happy. Being sad after you’ve been happy is the worst thing in the world.”

“The sad truth is that man's real life consists of a complex of inexorable opposites—day and night, birth and death, happiness and misery, good and evil. We are not even sure that one will prevail against the other, that good will overcome evil, or joy defeat pain. Life is a battleground. It always has been and always will be; and if it were not so, existence would come to an end.”
