Jiaoguan Gangzong — Translation Notes

These notes record recurring translation decisions for the Ru-Yi English translation of Ouyi Zhixu’s Jiaoguan Gangzong (教觀綱宗, Taishō T46, no. 1939), with reading notes drawn throughout from Zhixu’s own commentary, the Jiaoguan Gangzong Shiyi (教觀綱宗釋義, Xuzangjing X57, no. 974). They exist so that this treatise’s dense classification vocabulary — much of it the very scaffolding the rest of Tiantai doctrine hangs on — stays consistent across all five parts, and so that later Tiantai texts on this site can inherit these renderings rather than re-coin them.

The text and its author

Ouyi Zhixu (蕅益智旭, 1599–1655) was a late-Ming dynasty monk and one of the four eminent masters of that era, though he is not usually counted a strict lineage-holder of any single school — his own writing draws on Tiantai, Chan, Pure Land, and Vinaya alike. The Jiaoguan Gangzong is nonetheless his most concentrated statement of Tiantai doctrine: a short treatise, expanded from an earlier wall-chart of his own devising (as his own opening lines explain), that compresses the entire Tiantai classification of the Buddha’s teaching career — the Five Periods, the Eight Teachings, and the Four Teachings of Content worked out in full doctrinal detail, complete with each teaching’s own six identities and ten modes of contemplation — into a single continuous outline meant to be memorized. It is often read as the standard doctrinal key to the rest of the Tiantai corpus, including the far longer works already translated on this site.

The companion commentary, the Jiaoguan Gangzong Shiyi, is Zhixu’s own explanation of his own treatise, expanding on nearly every compressed term and parenthetical gloss in the base text. Its structure tracks the base text closely enough that every reading note on this collection’s five pages can be traced back to a specific passage of T1939.

Source and copyright

• Base text: Taishō T1939, via the CBETA digital edition. Commentary: Xuzangjing X974, also via CBETA. Zhixu died in 1655 — both texts have been in the public domain for well over three centuries, under any jurisdiction’s copyright term. CBETA’s own transcription is distributed under a non-commercial-use license, consistent with how this non-profit site already uses CBETA-sourced text across every other translation project here.
• No prior complete English translation of either text is known to exist. This is an original translation made directly from the Chinese.

Structure

The base text (479 lines in its CBETA markdown source) has no fascicle divisions of its own — it is a single short continuous treatise. This collection splits it into five pages at the treatise’s own major doctrinal joints, not at any division CBETA or Zhixu imposed:

1. Part 1 (base text lines 24–149): the opening pairing of teaching and contemplation, the Eightfold outline, the Five Periods (general and specific readings, with Guanding’s polemic against a rigid twelve-year dating), and the Four Teachings of Method — the sudden, gradual, secret, and indeterminate.
2. Part 2 (lines 150–222): the Tripiṭaka teaching in full.
3. Part 3 (lines 224–290): the shared teaching in full.
4. Part 4 (lines 292–354): the distinct teaching in full.
5. Part 5 (lines 356–461): the perfect teaching in full, the fivefold transfer/graft/converge/gather/borrow scheme binding all Four Teachings together, and the closing dialogue.

Every page’s own bilingual source/translation columns were verified against the CBETA base text for 100% character coverage; the whole five-page set was additionally cross-checked against the full base text (lines 24–461) as a single merged run, with no gaps found. Zhixu’s commentary appends one further section, “On the Substance of the Three Kinds of Loving-Kindness” (附三慈體相), that answers no specific line of the base treatise; it is described but not translated in full on Part 5, since this project’s coverage requirement applies to the base text itself.

Terminology inherited from this site’s three earlier Tiantai projects

This treatise shares its entire technical vocabulary with the Mo-ho Chih-kuan (sutras/mohe-zhiguan/), the Shi Chan Boluomi Cidi Famen (sutras/shi-chan-boluomi/), and the Xiuxi Zhiguan Zuochan Fayao Jiangshu (sutras/xiao-zhiguan-jiangyi/) — indeed, Zhixu’s own closing dialogue on Part 1 names the first two of these by title as the textbooks for the gradual and sudden contemplations his own treatise organizes. Every term below was already established by one or more of those three projects and is reused here without modification:

Terminology coined for this project

The following terms had no fixed rendering anywhere on this site before this project and are recorded here for later Tiantai texts — especially anything drawing on the Fahua Xuanyi or Fahua Wenju, which this treatise cites repeatedly — to inherit rather than re-coin.

A note on the “current single thought”

Zhixu’s reading note on the perfect teaching’s ten modes of contemplation (Part 5) explains why every mode of the perfect teaching’s own contemplation is anchored to “the current single thought of mind” (現前一念心) rather than a grander object — this is the same analytical move already tracked at length in the Mo-ho Chih-kuan translation notes’ entries for 一念三千 and 現前一念. Readers encountering this treatise before the Mo-ho Chih-kuan may want to read that project’s fascicle 5 notes alongside this collection’s Part 5 for the fuller argument; this project’s own reading note gives only the condensed version Zhixu’s commentary itself provides for the Jiaoguan Gangzong.

Keep this table growing as later Tiantai texts on this site draw on this treatise’s own vocabulary — add a row rather than improvising a fresh translation of a term that already has an entry here.
