Guìwěi kǒujué 檜尾口訣
Oral Decisions Recorded at Hinoki-no-o by 實慧 (記)
About the work
A single-fascicle kuden 口訣 (Jp. kuketsu, “oral decisions”) compiled by Jitsue 實慧 (786–847), Kūkai’s senior disciple and the first abbot of Hinoki-no-o 檜尾 (also written 桧尾), the mountain hermitage that Kūkai assigned to him on Kōyasan. The work records Jitsue’s transcriptions of the oral instructions he received directly from Kūkai on a sequence of essential Shingon ritual procedures: the Buddha-eye method (fóyǎn fǎ 佛眼法), the Vajra-longevity method (jīngāng shòumìng fǎ 金剛壽命法), the five wrathful kings (wǔ dàzūn 五大尊), the six-foot honored ones (liùzú zūn 六足尊), the homa (護摩) variations, intercalary-month and small-month star-conjunction tables, and so on.
Abstract
Authorship and dating: the terminal colophon is unusually explicit. It reads: “The above is an extract of the oral decisions of Sōzu Jitsue that he received in transmission from the Daishi [Kūkai] on Kōyasan; most reverently to be honoured.” (右抄實惠僧都於高野大師所傳習之口決也。尤可尊重々々々々). The composition window must lie between Kūkai’s establishment of the Kōyasan monastery (Kōnin 7 = 816, with serious construction underway from 821 onward) and Jitsue’s own death (847). A later copyist’s note records: “Kenkyū 6 (1195), 11th month, 6th day, copying completed at the Nōryōbō at the hour of the Tiger.” (建久六年十一月六日寅時許於納涼房書寫了).
Doctrinal content: the table of contents lists 11 main sections of procedure, each crucial for Shingon esoteric practice. The opening section, on the Buddha-eye method (Buddhalocanā — the principal female vidyārājñī of the Buddha-family), gives detailed instructions for two variant kantsui-yō 寂災 (calamity-pacifying) procedures: in the first, the practitioner visualizes the seed-syllable vaṃ (Vairocana) on the central altar together with bhrūṃ (or bhrūṃ-Locanā) as the Buddha-eye seed-syllable, then visualizes the transformation of Vairocana into the Buddha-eye deity. The work proceeds through the wrathful-deity procedures, the enmity-form rituals (yuàn-xíng 怨形), the seven-day non-untying-of-the-boundary (qī-rì děng bù-jiě-jiè 七日等不解界) procedure, homa variations, intercalary-month adjustments, and concludes with the assignment of ākhādhi 閼伽 (water-offering) verses, the substantive instructions specific to each Buddha-family (zhū-bù xiāng-yìng wù 諸部相應物), and the xī-zāi 息災 (calamity-cessation) mantra-corpus.
The work is one of the earliest extant Japanese Shingon kuden records and the principal documentary witness to Hinoki-no-o lineage practice — the Kōyasan branch of Kūkai’s transmission that continued through Jitsue’s successors Shinzei 眞濟 and Shinga 眞雅 and ultimately fed into the Ono-ryū 小野流 of Heian Shingon.
Translations and research
- No substantial Western-language secondary literature located.
- The Hinoki-no-o transmission is treated in Japanese scholarship as part of the early Kōyasan history; standard sources are Kōyasan-shi and the Mikkyō daijiten s.v. Jitsue 實慧.
Other points of interest
The text exemplifies the oral-decision (kuketsu) genre that became the dominant medium of Heian and Kamakura Shingon scholastic transmission: not a treatise but a record of master-to-disciple ritual instruction, preserving the specific procedural variants that distinguish one ryū (transmission lineage) from another.
