AFTER THE MOON-VIEWING,
MY SHADOW WALKING HOME
ALONG WITH ME.
-Sodo

A full moon -- that has become traditional in Zen. On the full-moon night the Zen seekers don't sleep, they walk into the mountains where the moon has made waterfalls look as if silver is falling, where the moon has made the whole surroundings a dream.
This is called moon-viewing; it is a tremendously aesthetic experience.
Such silence. Nobody is with me, just my shadow walking along with me. After seeing this whole beautiful world, when you enter into your home nobody will be with you, not even your shadow. Your aloneness will be total.
Every meditation is a preparation for enjoying the aloneness which is our nature.
