Tiantai Commentary

The Tiantai school, founded by the great Chinese master Zhiyi (538–597), takes the Lotus Sutra as the supreme expression of the Buddha’s teaching. Zhiyi’s monumental commentaries – the Fahua Xuanyi (Profound Meaning of the Lotus Sutra), the Fahua Wenju (Words and Phrases of the Lotus Sutra), and the Mohe Zhiguan (Great Calming and Contemplation) – established a comprehensive philosophical system based on the sutra’s teachings.

Central to Tiantai interpretation is the doctrine of the “three thousand realms in a single moment of life” (ichinen sanzen), derived from the Ten Suchnesses passage of Chapter 2. The Tiantai school also developed the classification of the sutra into the Trace Teaching (Chapters 1–14) and the Essential Teaching (Chapters 15–28), a framework that has shaped all subsequent East Asian readings of the text.

Commentary from the Tiantai tradition will be added to this section as the project develops.
