Yīchéng fóxìng huìrì chāo 一乘佛性慧日抄
A Sun-of-Wisdom Digest on the One-Vehicle Buddha-Nature attributed to a Gangō-ji śramaṇa “Sō” 宗
About the work
A one-fascicle Heian Japanese Sanron 三論 (Mādhyamika) tract defending the doctrine of universal Buddha-nature (fóxìng 佛性) and the one-vehicle (yīchéng 一乘) teaching against the Hossō wǔ-xìng 五性 (Five Lineages) doctrine. Preserved in Taishō vol. 70 (no. 2297). The Japanese title is Ichijō busshō enichi shō. The Taishō text’s authorial signature reads “元興寺沙門宗撰” (“composed by the Gangō-ji śramaṇa Sō [宗]”) — an unusually terse attribution. The catalog metadata records no author. Both the precise identity of the author and the precise date are uncertain.
Prefaces
The work opens with a brief authorial-style preface, signed “元興寺沙門宗撰”:
夫入於一心大有二門。一三乘五性敎。則法相宗。二一乘佛性宗。如三論敎。然以性欲萬殊隨根非一。原乎其本何有異敎。故今隨敎總觀聖心。隨機攝化終入一道。以此爲宗。群生不窮大悲無限。力用奧弘衆機斯應。豈捨一分非授圓果。今少論之
“For entering the One Mind there are in general two gateways: one is the teaching of three vehicles and five lineages — namely, the Hossō school; the second is the teaching of one vehicle and Buddha-nature — like the Sanron teaching. Yet since dispositions and inclinations are myriadly distinct and faculties are not one, what at root could be a different teaching? Therefore now, following each teaching, we observe the holy mind in its totality; following each capacity, we draw all in and lead them to enter the single Path. Take this as the school’s foundation: sentient beings without limit, great compassion without bound; the strength of function reaches profoundly to all and answers every capacity. How could we abandon any part and not bestow the perfect fruit? Now let us briefly discuss this.”
The body then proceeds in question-and-answer form, with the first question presenting the Hossō opponent’s position: the Saṃdhinirmocana-based defence of the five lineages including the agotra (無種姓) lineage of beings incapable of liberation.
Abstract
The Yīchéng fóxìng huìrì chāo is a polemical tract defending the Tathāgatagarbha universal Buddha-nature doctrine against the Hossō five lineages doctrine. The contested point — whether there exists a class of beings (icchantika / 一闡提) permanently incapable of Buddhahood — was the central late-Tang and Heian doctrinal controversy between the universalist Sanron-Kegon-Tendai-Shingon schools and the particularist Hossō school. The huìrì (慧日, “sun of wisdom”) imagery in the title is a standard Sanron metaphor for the comprehensive illumination provided by the Mūlamadhyamakakārikā’s analysis.
The authorial signature “元興寺沙門宗” is enigmatic. It cannot easily be identified with any named Gangō-ji monk in standard biographical sources. Some Edo-era scholars proposed identification with 玄叡 (Gen’ei, d. 840), the principal Gangō-ji Sanron systematiser (KR6o0081), on the supposition that “宗” might be a sobriquet or abbreviated name-element. Others have proposed identification with the later Gangō-ji Sanron scholar 玄日 Gennichi (10th c.) or with 護命 Gomyō (750–834). Without external evidence the attribution remains unresolved, and the work is consequently listed in the Kanripo catalog metadata without an authorial entry.
The doctrinal positioning — accepting Hossō and Sanron as parallel “two gateways into the one mind” and aiming at synthesis on the basis of universal Buddha-nature — is characteristic of the Heian-period accommodationist Sanron as distinct from the more polemical Sui-Tang Sanron of Jízàng. This places the work in the c. 800–1000 range; precise dating is not possible.

Other points of interest
The work is a documentary witness to the persistence of the Buddha-nature-vs-five-lineages controversy in early-Heian Japan, well after the corresponding Sino-Indian debates had largely subsided. The Heian-Sanron accommodationist stance — accepting Hossō as a partial truth while insisting on Sanron’s universal salvation — anticipates the later Tendai hongaku 本覺 doctrine and the more synthetic Esoteric-Sanron-Yogācāra theologies of the Heian period.
