Do not be daunted by the enormity of the world’s grief.
Do justly, now.
Love mercy, now.
Walk humbly, now.
You are not obligated to complete the work,
but neither are you free to abandon it.
[Talmud]

This is the third movement from Beethoven’s Tempest Sonata, played by Wilhelm Kempff. It’s a beautiful black and white video and even on YouTube you can hear how luminous the performance is.
