In this talk, Will Kabat-Zinn explores the deeper meaning of the first five lines of the poem, "Guidepost of Silent Illumination" by Zen Master Hongzhi:

Silent and serene, forgetting words, bright clarity appears before you.
When you reflect it you become vast, where you embody it you are spiritually uplifted.
Spiritually solitary and shining, inner illumination restores wonder,
Dew in the moonlight, a river of stars, snow-covered pines, clouds enveloping the peak.
In darkness it is most bright, while hidden all the more manifest.
~translated by Taigen Dan Leighton
