Bringing the Tiantai Tradition into English
Two of the most influential Buddhist texts in East Asian history have, until recently, been almost inaccessible to English-language readers. That is no longer the case.
The Mohe Zhiguan (摩訶止觀) and the Fahua Xuanyi (法華玄義) are the two foundational works of Master Zhiyi (538–597 CE), the architect of the Tiantai school of Mahāyāna Buddhism—the tradition that gave us the doctrine of ichinen sanzen (three thousand realms in a single thought-moment), the Threefold Truth, the Ten Suchnesses, and the systematic meditation framework that has shaped Chinese, Korean, and Japanese Buddhism for fourteen centuries. Together with the Fahua Wenju (法華文句), Zhiyi’s line-by-line commentary on the Lotus Sūtra, they form what the tradition calls the Three Great Works—doctrinally complementary, historically inseparable, and until now scattered across academic translations whose technical apparatus often kept the contemplative reader at the threshold.
The Tiantai Teachings Project is a long-form effort to bring the Three Great Works into English as integrated, source-grounded volumes that serve both scholars and practitioners. Two are now live on Amazon.
Mohe Zhiguan, Volume I: The Foundation
For more than fourteen centuries, the Mohe Zhiguan has stood as the towering peak of East Asian Buddhist meditation manuals. Delivered by Master Zhiyi in 594 CE at the Yuquan Monastery and recorded by his disciple Guanding, the text integrates the encyclopedic depth of Mahāyāna philosophy into a step-by-step contemplative system through which the practitioner enters the realization of the Threefold Truth.
This first volume presents Chapters 1 through 8—the foundation of the work—covering the arousing of bodhicitta, the Four Samādhis, the Six Identities, and the vast Ten Objects of Contemplation that occupy the work’s central architecture. Classical Chinese source passages are reproduced before each English rendering, with line-references to the Taishō canon. The translation foregrounds the systematic doctrinal architecture of Tiantai thought, preserving technical precision while deploying a lucid English vocabulary that lets the reader engage the text as the contemplative manual Zhiyi intended.

Fahua Xuanyi: The Philosophy of the One Vehicle
The Fahua Xuanyi is the Mohe Zhiguan‘s indispensable companion. Where the Zhiguan is the practice manual, the Xuanyi is the doctrinal architecture that the practice instantiates. It is the text in which Zhiyi develops the Five Periods of the Buddha’s preaching career, the Eight Teachings that map the doctrinal categories of the entire Mahāyāna canon, and the Ten Suchnesses that give the Tiantai tradition its analytical instrument for any phenomenon whatsoever.
This is the philosophical foundation of the One Vehicle (ekayāna) doctrine—the Lotus Sūtra‘s central claim that all the apparently divergent paths of Buddhist practice are, at their root, the single path of universal awakening. Subtitled The Philosophy of the One Vehicle, this edition presents the Xuanyi in the same source-grounded format as the Mohe Zhiguan, with bilingual citations and the full technical apparatus.
What’s coming next
The third volume of the Three Great Works—Fahua Wenju (T.1718), Zhiyi’s line-by-line commentary on the Lotus Sūtra—is in production and will be available later this year. Together, the three volumes form a complete English-language entry into Tiantai’s foundational corpus.
A separate forthcoming title, The Stone and the Machine: A Tiantai Buddhist Reading of Artificial Intelligence, applies the same Tiantai framework to the question that this technological moment is asking. More on that when it lands.
