In the meanwhile the Sixth Patriarch, who had gone to the South, arrived at the Fah Sing Monastery in Kwang Cheu, where Yin Tsung (In-shu), the abbot, was giving lectures on the Mahayana sutras to a number of student monks. It was towards evening that he happened to overhear two monks of the Monastery discussing about the flag floating in air. One of them said: "It is the wind that moves in reality, but not the flag." "No," objected the other, "it is the flag that moves in reality, but not the wind." Thus each of them insisted on his own one-sided view, and came to no proper conclusion. Then the Sixth Patriarch introduced himself and said to them: "It is neither the wind nor the flag, but your mind that moves in reality." Yin Tsung, having heard these words of the stranger, was greatly astonished, and thought the latter should have been an extraordinary personage. And when he found the man to be the Sixth Patriarch of Zen, he and all his disciples decided to follow Zen under the master. Consequently Hwui Nang, still clad like a layman, changed his clothes, and began his patriarchal career at that Monastery. This is the starting-point of the great development of Zen in China. 12. Missionary Activity of the Sixth Patriarch. As we have seen above, the Sixth Patriarch was a great genius, and may be justly called a born Zen teacher. He was a man of no erudition, being a poor farmer, who had served under the Fifth Patriarch as a rice-pounder only for eight months, but he could find a new meaning in Buddhist terms, and show how to apply it to practical life. On one occasion, for instance, Fah Tah (Ho-tatsu), a monk who had read over the Saddharma-pundarika-sutra[FN#46] three thousand times, visited him to be instructed in Zen. "Even if you read the sutra ten thousand times," said the Sixth Patriarch, who could never read the text, "it will do you no good, if you cannot grasp the spirit of the sutra." "I have simply recited the book," confessed the monk, "as it is written in characters. How could such a dull fellow as I grasp its spirit?" "Then recite it once," responded the master; "I shall explain its spirit." Hereupon Fah Tah began to recite the sutra, and when he read it until the end of the second chapter the teacher stopped him, saying: "You may stop there. Now I know that this sutra was preached to show the so-called greatest object of Shakya Muni's appearing on earth. That greatest object was to have all sentient beings Enlightened just as He Himself." In this way the Sixth Patriarch grasped the essentials of the Mahayana sutras, and freely made use of them as the explanation of the practical questions about Zen. [FN#46] One of the most noted Mahayana sutras, translated by Dharmaraksa (A.D. 286) and by Kumarajiva (A.D. 406). The reader has to note that the author states the essential doctrine in the second chapter. See " Sacred Books of the East," vol. xxi., pp. 30-59. 13. The Disciples under the Sixth Patriarch.
