When you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight.
Some of you say, "Joy is greater than sorrow," and others say, "Nay, sorrow is the greater."
But I say unto you, they are inseparable.
Together they come, and when one sits alone with you at your board, remember that the other is asleep upon your bed.
Verily you are suspended like scales between your sorrow and your joy.

Khalil Gibran, The Prophet
