Daniel Charles, “Gloses sur le Ryoan-ji,” translated by Kouzo Watanabe, Episteme, Asahi Publishing Co., Tokyo, November 1978, p.43. He also quotes immediately afterwards from Will Petersen’s, “We are able to perceive nothingness only through the form” and this is “one of the most fundamental paradoxes in Buddhist thought.” (translated from the Japanese by Kouzo Watanabe.)
