full moon

"The time when the moon appears is not necessarily night. Night is not necessarily dark. Do not be limited by the narrow views held by human beings. Even when there is no sun or moon, there is day and night. Sun and moon are not day and night; each is at it is." 

Tsuki (the moon) by Master Dogen, 1243, translated by Mel Weitsman and Kazuhaki Tanahashi (from "Moon in a dewdrop", North Point Press)
