Nonexistence contains existence. Love / encloses beauty. Brown flint and gray steel have orange candlelight in them. Inside / fear, safety. In the black pupil of the eye, many brilliancies.
—Jalal al-Din Rumi (1207–1273), from Paradox. The Soul of Rumi: A New Collection of Ecstatic Poems, translated by Coleman Barks, 2001.

Disciple: Does the cold flint contain the warm flame, Master?
Master: Tiny, sleeping monks with disposable lighters.
