With regard to sūtra that literally means thread (Fan-hsien) signified by the Chinese word Ching, Chih-i explains that thread can function to link teaching, practice and doctrine, so that these aspects are not scattered. In addition, thread also conveys the meaning sewing. By sewing up teaching, sentences and phrases can be put in order, so that one can expound the dharma accordingly. Thread can also function to sew up practice. When one follows the warp, one’s practice is correct. When one disobeys the warp, one’s practice is deviant. Thread can also sew up the principle. What is not coherent with the principle falls into sixty-two kinds of evil. What is coherent with the principle integrates with the ultimate Path as the One Buddha-vehicle. (Vol. 2, Page 394)
