Your joy is your sorrow unmasked.
And the selfsame well from which your laughter rises was oftentimes filled with your tears.
And how else can it be?
The deeper that sorrow carves into your being, the more joy you can contain.
Verily you are suspended like scaled between your sorrow and your joy.
When the treasure-keeper lifts you to weigh his gold and his silver,
needs must your joy or your sorrow rise or fall.
-Kahlil Gibran, The Prophet
