Shōken 聖憲 (conventionally 1307–1392) — Nanbokuchō-period Japanese Shingon scholar-monk of the Daigo-ji Sanbō-in 醍醐三寶院 tradition, principal Daigo Sanbō-in scholastic of the fourteenth century and a major figure in the medieval Shingon doctrinal tradition.
His two major works preserved in the Taishō are:
- Daisho hyakujō dai-san jū 大疏百條第三重 (KR6t0244, T79n2538) — a ten-fascicle one-hundred-clause scholastic-doctrinal exposition on the Mahāvairocanasūtra Commentary (大日經疏 Dàrìjīng shū) of Yīxíng, organized in three successive “depths” (重) of which the present third-depth treatment is the most elaborated. The work treats fundamental Shingon-doctrinal topics through systematic question-and-answer.
- Jishō seppō 自證説法 (KR6t0245, T79n2539) — a single-fascicle doctrinal essay on the question whether at the jishō-gokui (self-realisation ultimate-position) the Buddha properly preaches the present sūtra. This is one of the central doctrinal disputes within the Shingi-Shingon and the Daigo Sanbō-in scholastic traditions.
He stands within the Daigo Sanbō-in lineage that descends from the Heian masters and through Raiyu’s reformist Shingi-Shingon doctrinal innovations. The traditional dating 1307–1392 places him in the Nanbokuchō / early-Muromachi political-religious moment, a key period in the doctrinal consolidation of the medieval Shingon scholasticism.
