“Of joys departed,
Not to return, how painful the remembrance!”

Original: (de) Jüdische Geschichte ist voll von Leiden und schrecklichem Kummer. Aber sie ist auch voll von unermesslicher Freude. Wir ehren das Leiden durch Erinnern. Wir ehren die Freude durch Feiern.

Original: A minha alegria é tão dolorosa como a minha dor.

The Saviors of God (1923)
Context: From every joy and pain a hope leaps out eternally to escape this pain and to widen joy.
And again the ascent begins — which is pain — and joy is reborn and new hope springs up once more. The circle never closes. It is not a circle, but a spiral which ascends eternally, ever widening, enfolding and unfolding the triune struggle.

Variant: Find a place inside where there's joy, and the joy will burn out the pain.
