Speaking of all the phenomena embraced in the five Chinese characters of Myō, Hō, Ren, Ge, and Kyō, the character Kyō is the king of all sūtras because it contains all the Buddhist sūtras in this single character. During 50 years or so after the Buddha appeared in this world, He preached the 80,000 Holy Teachings. In the period when the human life span was 100 years, He passed away at midnight on February 15 at the age of 80. During the summer season of 90 days, from April 8 to July 15, 1,000 arhats assembled in a place to write down what the Buddha had expounded during His lifetime and to compile the scriptures. Afterwards, during the Age of the True Dharma, the first 1,000 years after the extinction of the Buddha, the Buddhist scriptures spread throughout India, but they were not yet introduced to China. Then in the 15th year of the Age of the Semblance Dharma, during the reign of Emperor Hsiao-ming of Later Han China (67 A.D.), the Buddhist scriptures were brought to China for the first time. By the time of Emperor Hsüan-tsung of the T’ang dynasty (730), the number of translators who came from India amounted to 176 and the total of sūtras, precepts, and discourses they brought numbered as many as 1,076 in 5,048 fascicles and 480 satchels. These scriptures are all followers of the character “kyō” of the Lotus Sūtra.
