Sìshí tiè jué 四十帖決
Forty-Folder Decisions by 長宴 (記)
About the work
The fifteen-fascicle (originally forty tiè / fascicle-folders) canonical kuden compendium of mid-Heian Tendai esoteric (Taimitsu 台密) procedure and doctrine, compiled by Chōen 長宴 (1016–1081), disciple of Kōkei 皇慶 (皇慶) and founder of the Renge-ryū sub-lineage. The work is the single largest collection of mid-Heian Taimitsu oral-transmission material and the principal medieval reference for the Tani / Kawa-ryū tradition.
Abstract
Authorship. The header is explicit: “Recorded by Chōen 長宴記”. The work systematically presents Chōen’s record of his teacher Kōkei’s kuden — together with material from his fellow disciples and from his own consultation of canonical and procedural sources.
Date. Compiled across Chōen’s mature career, c. 1040s–1081 CE. Modern scholarship places its primary compilation phase in the 1050s–1060s.
Structure. The work’s table of contents organizes the forty tiè into ten “volumes” (juàn 卷, as transmitted in Taishō), each grouping a thematically-related set of fascicles:
- Volume 1 (2 tiè, fascicles 1–2): Foundational doctrinal premises of the esoteric way.
- Volume 2 (3 tiè, fascicles 3–5): Vajradhātu and Garbhadhātu primary procedures.
- Volume 3 (2 tiè, fascicles 6–7): Maṇḍala construction and consecration.
- Volume 4 (3 tiè, fascicles 8–10): Major kanjō (consecration) procedures.
- Volume 5 (4 tiè, fascicles 11–14): Sokushinjōbutsu 即身成佛 (this-body-becoming-Buddha) doctrine and the Pañcākārābhi-saṃbodhi meditation.
- Volume 6 (2 tiè, fascicles 15–16): Specific deity-rites.
- Volume 7 (4 tiè, fascicles 17–20): Specific deity-rites (continued).
- Volume 8 (5 tiè, fascicles 21–25): Susiddhi-sūtra and gōhō protective rites.
- Volume 9 (1 tiè, fascicle 26): Homa (護摩) procedure.
- Volume 10 (2 tiè, fascicles 27–28): Annual liturgical cycle.
- Subsequent fascicles 29–40 cover supplementary doctrinal-procedural matters.
Genre and significance. The Sìshí tiè jué is the largest single kuden (口傳, “oral-transmission”) record in the medieval Tendai-esoteric corpus, and Chōen’s preservation of his teacher Kōkei’s oral teaching is what allows the historical reconstruction of mid-Heian Tani-ryū doctrine and procedure. The work also preserves valuable material on the institutional history of Hiei-zan Taimitsu: who studied with whom, which procedures were transmitted in which sub-lineage, what doctrinal questions were debated and how they were resolved.
The work is cited extensively in later Taimitsu literature, including the encyclopedic Xínglín chāo 行林抄 of Seinen (KR6t0109) and the Xīlán shíyè jí 溪嵐拾葉集 of Kōshū (KR6t0110).

Other points of interest
The work’s compilation history is notable: Chōen organized the material as forty independent paper-folders (tiè 帖, “folders” or “booklets”) rather than as a single bound volume — a format that allowed continued addition and revision throughout his lifetime. The Taishō editors reorganized these into fifteen-fascicle continuous-text format for printing, but the work’s discontinuous-aggregative character is still visible in the abrupt topic-shifts between adjacent fascicles.
