One Hundred Records of the Great Teacher T’ien-t’ai, The ［国清百録］ (Chin Kuo-ch’ing-pai-lu;  Kokusei-hyakuroku): A collection of 104 historical records and documents that includes the monastic rules of discipline in the T’ien-t’ai school, imperial edicts, and correspondence between T’ien-t’ai and Emperor Hsüan of the Ch’en dynasty (557–589), Emperor Yang of the Sui dynasty (581–618), and eminent priests such as Chi-tsang. Its compilation was planned and initiated by Chih-chi, a disciple of T’ien-t’ai, but because Chih-chi died while the work was in progress, it was continued by Chang-an, T’ien-t’ai’s successor, and completed around 605. Together with The Biography of the Great Teacher T’ien-t’ai Chih-che of the Sui Dynasty, which was also compiled by Chang-an, it is regarded as an essential source for the study of T’ien-t’ai and his school in its early phase.
