Yuánmìzōng èrjiào míngmù 圓密宗二教名目
Doctrinal Nomenclature of the Two Teachings of the Round-Esoteric School by 惠鎭 (撰)
About the work
A single-fascicle doctrinal nomenclature manual (míngmù 名目) organized as a series of question-and-answer items, explaining the technical terminology of the Tendai-Esoteric synthesis (Yuánmì 圓密, “round-and-esoteric”) tradition that Saichō and Ennin had developed in the early Heian and that had become the core Hiei-zan doctrinal framework. The work is attributed to Echin 惠鎭 (Enkan 圓觀, 1281–1356) of Genna-ji / Gennō-ji 元應寺, the Tendai preceptor closely associated with Emperor Go-Daigo and a leading figure of the late Kamakura-Nanboku-chō Tendai establishment.
Abstract
Authorship. The catalog meta identifies the author as 惠鎭 (Echin), and the early collation note records the manuscript-tradition as derived from “the imperial original at Gennō-ji” — Gennō-ji 元應寺 being Echin’s monastic base in the imperial capital (established in 1319 by Emperor Hanazono and Empress Eifukumon-in).
Date. No internal date. The manuscript was copied at Hossō-ji Vinaya cloister on the 5th day of the 12th month of Jōwa 5 (己丑 jǐchǒu) = January 1350 CE by Sōchi 宗智, and collated the next day. Subsequent copy-marks document the work’s transmission through Tenmon 19 = 1550 (Jōshun 定舜’s copy), Kyōhō 8 = 1723 (天忠 Tenchū, age 32), and Kyōhō 9 = 1724 (the present version’s collation). The composition must therefore predate Jōwa 5 (1350) and is most plausibly placed during Echin’s mature activity at Gennō-ji, that is between 1319 (founding of Gennō-ji) and 1356 (Echin’s death). notBefore = 1319, notAfter = 1356 is conservative.
The work’s structure is catechetic, framed as a sequence of “question — answer” exchanges that progressively unfold the doctrinal vocabulary. The opening question sets out the master dichotomy of the title: “‘The two teachings’ — what are they?” Answer: “One: the manifest-display teaching (顯示教); two: the secret teaching (祕密教).” The body then unfolds:
(1) The manifest-display teaching is identified with the Three-Vehicles teaching (三乘教), covering the Āgama and Saṃdhinirmocana-sūtra corpora. The argument runs: “These sūtras explain only the practical aspect of the three vehicles; they do not clarify the round-fusion of the worldly and ultimate truths. Therefore they are called manifest-display teaching.”
(2) The secret teaching is then sub-divided into two: (i) the principle-only secret teaching (唯理祕密教) — Lotus, Mahāparinirvāṇa, Avataṃsaka, Vimalakīrti, and the other Mahāyāna sūtras — which “explain only the round-fusion of the worldly and ultimate truths, but have not yet manifested the event-and-principle round-fusion of the dharma-realm*;*” and (ii) the event-and-principle secret teaching (事理祕密教) — Mahāvairocana, Vajraśekhara, Susiddhi-kara — which “manifest both worldly-and-ultimate round-fusion and event-and-principle round-fusion, the full secret-treasury of the Three Mysteries.”
The work then proceeds through the standard Tiantai-Esoteric terminology: the Eight Teachings (八教) — both huà-yí (transformation-method) and huà-fǎ (transformation-doctrine) — the Five Flavors (五味), the relation between the Lotus’s One-Vehicle and the Esoteric Three-Vehicles formula, the Two Mandala (兩部 manḍala — Garbha-dhātu and Vajra-dhātu), the Three Mysteries (三密), and the One-Vehicle Buddha-vehicle of the Lotus in relation to the Six Great Elements of Shingon.
The work is a late Kamakura-Nanboku-chō Tendai doctrinal pedagogical text, designed to fix the canonical terminology for the yuánmì synthesis. Its modest scope (one fascicle) and catechetic format made it a useful introductory text for Hiei-zan novice training.

Other points of interest
The work’s structural attribution of the Lotus and Avataṃsaka to the “principle-only” secret teaching — i.e. as a category intermediate between the exoteric and the fully-esoteric Vairocana-cycle — represents a refined version of the late-medieval Tendai yuán-mì synthesis, more nuanced than the simpler “Tendai and Shingon are equal” position of KR6t0070 (Shōshin’s late-Heian formulation) and reflecting the doctrinal consolidation achieved by Annen (KR6t0095) and developed in the medieval Tendai exegetical lineage.
