On Sado Island, I was put in a small six-foot square shrine in the midst of a lonely cemetery called Tsukahara located between a field and a mountain remote from the village. The roof was warped, and the walls were cracked so that it rained inside just like outside, and snow piled up within. As it was without straw mats and a Buddhist statue not enshrined, I respectfully set up a statue of the Original Śākyamuni Buddha, which I had possessed for a long time, and chanted the Lotus Sūtra day after day, wearing a raincoat made of rice straw and holding an umbrella. No one visited me and hardly any food was given to me for four years. It was the same as for Su Wu of China, who survived 19 years of captivity in a barbarian nation by wearing a raincoat made of rice straw and feeding himself with snow.
