On Joy and Sorrow

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.
                                                                                   --Kahlil Gibran, The Prophet, 1923

With much wisdom comes much suffering;
the more knowledge, the more grief.
                               --Ecclesiastes 1:18
