Suigan Kashin (Ts‘ui-yen K‘ê-chên)[6.79] was a disciple of Zimyo (Tz‘u-ming), 986–1040, who was one of the greatest Sung masters and under whom the Rinzai school of Zen was divided into two branches, Woryu (Huang-lung) and Yogi (Yang-ch‘i).[6.80] Kashin was quite proud of being one of the disciples of the master, he was not yet really a master himself, but he thought he was. When he had a talk with another of Zimyo’s disciples, he was found out and laughed at. When they were having a walk together one day, they discussed Zen. His friend picked up a piece of a broken tile and putting it on a flat rock, said, “If you can say a word at this juncture, I will grant your really being Zimyo’s disciple.” Kashin wavered, looked this way and that, trying to make some answer. His friend was impatient, who broke out, “Hesitating and wavering, you have not yet penetrated through illusion, you have never yet even dreamt as to what the true insight of Zen is.” Kashin was thoroughly ashamed of himself. He at once returned to the master who severely reproached him, saying that he came before the termination of the summer session, which was against the regulations. Full of tears, he explained how he was taken to task by his fellow-monk and that it was the reason why he was here even against the monastery rules. The master abruptly asked him: “What is the fundamental principle of Buddhism?” Replied Kashin, “No clouds are gathering over the mountain peaks, And how serenely the moon is reflected on the waves!” The master’s eyes flashed with indignation, and he thundered, “Shame on you! To have such a view for an old seasoned man like you! How can you expect to be delivered from birth-and-death?” Kashin earnestly implored to be instructed. Said the master, “You ask me.” Thereupon he repeated the master’s first question, “What is the fundamental principle of Buddhism?” The master roared, “No clouds are gathering over the mountain peaks, And how serenely the moon is reflected on the waves!” This opened Kashin’s eye, and another man was he after that. * * * * * Let me conclude with a sermon from Goso (Wu-tsu), of whom mention has already been made:
