Chih-i associates Ching (etymological meaning “warp”) with its opposite meaning “weft” (Wei). The meaning weft is also examined by Chih-i in these three perspectives.

1. In discussing the meaning warp and weft with reference to teaching, Chih-i holds that by means of the Worldly Siddhānta, what the Buddha expounds is called Ching, which forms warp, and what the bodhisattva weaves according to the teaching of the Buddha is called commentary, which forms weft. When the warp and weft are combined, the Buddhist canon that consists of teaching and commentary is thus established.
2. In discussing the meaning warp and weft with reference to practice, Chih-i delineates that the practice concerning wisdom forms warp, and the practice concerning severing defilement forms weft. The combination of warp and weft produces the text concerning the Eightfold Correct Path.
3. In discussing the meaning warp and weft with reference to principle, Chih-i goes on to say that the Buddha’s explanation of the Absolute Truth forms warp, and the Buddha’s explanation of the Worldly Truth forms weft. The combination of warp and weft gives rise to the text concerning the Twofold Truth. (Vol. 2, Page 393)
