These are the reading days before exams. One needs something that you can turn your attention to if the reading becomes too much. Graphic courtesy of the Metropolitan Museum, "Reading a Sutra by Moonlight" 17th century Sokuhi Nyoitsu (Jifei Ruyi). The poem that accompanies this picture is:
"Moon and white paper are of one color. The pupil of the eye and the ink are both black. The marvelous meaning, lodged in the circle, Is beyond comprehension."
