Wéishí xùnlùn rìjì 唯識訓論日記
Diary of Glossed Readings on the Treatise on Consciousness-Only by 光胤 (Kōin, 草)
About the work
A one-fascicle Muromachi-period Japanese Hossō 法相 personal study-diary on selected passages of the Chéng wéishí lùn (KR6n0016, T31n1585), drafted (草) by 光胤 (Kōin, 1396–1468). Preserved as T2265 (Taishō vol. 66). The work opens with a table of contents announcing exactly which sections of each juǎn are annotated: “此帖ニ註ス分 / 第一卷 數論段引明燈抄以顯輪集委細註之 / 勝論段註大綱 / 第四卷聞書四食滅定染淨三依略略也 / 第八卷縁生分別已下極略略” — “Sections annotated in this booklet: juǎn 1, the Sāṅkhya section is annotated in detail by drawing on the Myōtō-shō to clarify the Wheel Anthology; the Vaiśeṣika section is annotated in outline; juǎn 4, the kikigaki on the four foods, nirodha-samāpatti, and the defiled-and-pure three supports is brief; juǎn 8, the section from Conditioned arising and discrimination onward is treated with extreme brevity.”
Structural Division
CANWWW (T66N2265) lists two related texts: KR6n0016 Chéng wéishí lùn 成唯識論 (T31n1585) and KR6n0021 Chéng wéishí lùn lüèshū 成唯識論略疏 (T68n2267, Fujaku). The single kan selectively annotates juǎn 1 (Sāṅkhya–Vaiśeṣika polemic), juǎn 4 (four foods, nirodha-samāpatti), and juǎn 8 (pratītyasamutpāda).
Abstract
The Kunron nikki is the personal-notebook pendant to Kōin’s longer formal lecture-record KR6n0019 Yuishikiron monsho (T2264, 27 fasc.): where the Monsho records the kōkō 講講 lectures as delivered, the Nikki gathers his own background research on the heterodox-school polemics in juǎn 1 (the doxographical Sāṅkhya and Vaiśeṣika discussions of the Triṃśikā / Vijñaptimātratāsiddhi’s opening section), drawing especially on 善珠’s KR6n0031 Yuishiki gitō zōmyō-ki (T2261) and Zenju’s KR6n0107 / In’myōron-sho myōtō-shō 因明論疏明燈鈔 (T2270) for the doxographical apparatus.
The Sāṅkhya section preserves Kōin’s reconstruction of the twenty-five-categories (二十五諦) tradition and the six-generation lineage from Kapila 劫比羅 → 阿修利 → 般尸訶 → 興褐伽 → 優樓佉 → 跋婆利 → Īśvara-Kṛṣṇa 自在黑 (the author of the Suvarṇasaptati 金七十論). This is one of the most extended Muromachi-period Japanese treatments of Indian Sāṅkhya doxography, drawing entirely on Buddhist In’myō (Hetuvidyā) reference works rather than on Sāṅkhya sources themselves. It is a useful witness to the channels through which classical Indian non-Buddhist philosophical doxography reached medieval Japan via the Cí’ēnzōng commentarial apparatus.
The date-bracket adopted here (1430–1468) follows the same mature-period bracket as for KR6n0019 Monsho.
Translations and research
- No substantial dedicated secondary literature located. The work is referenced in modern Japanese surveys of Muromachi-Hossō scholasticism alongside the longer companion-piece KR6n0019.
Other points of interest
The opening moku-roku explicitly admits selective coverage (“juǎn 8 is treated with extreme brevity”), making this one of the more transparent examples in the canonical Hossō literature of a working scholar’s actual study-priorities — a partial witness to the doctrinal questions Kōin personally found worth deeper investigation.
