Record of the Secret Transmission of Siddham by 信範 Shinhan (撰)
About the work
A single-fascicle Siddham esoteric-transmission treatise by Shinhan 信範 信範, a Shingon-line scholar of the late Heian / early Kamakura period. The title — Shittan hi-den-ki — names the work’s distinctive frame: it presents the Siddham doctrinal apparatus as a secret oral transmission (祕傳 hi-den), with the implication that the deeper meaning of the script is not publicly accessible but reserved for initiated practitioners.
Abstract
The work covers the standard Siddham letter corpus but with esoteric / mantric emphases that depart from the more philological orientation of Annen, Myōkaku, and Shinkaku. Particular attention is given to: (1) the bīja correspondences of each letter to the deities of the Garbha- and Vajra-dhātu maṇḍalas; (2) the visualization practices associated with each letter; (3) the breathing and pronunciation techniques for the maximally efficacious recitation of the bīja; (4) the dhāraṇī corpus for ritual application.
The work belongs to a category of late-Heian / early-Kamakura Shingon esoteric transmission-texts that present doctrinal material as secret oral teaching — a category that includes much of the Daigo-ji and Kōya-san ōkishō 御記抄 literature. Such works are doctrinally and historically valuable as evidence for what was orally transmitted but not written down in the formal Shingon canon — though their secrecy framing must be understood as a doctrinal-rhetorical mode rather than a literal claim of confidentiality.
Date. Shinhan’s precise lifedates are not securely attested. The work is generally placed in the late 12th / early 13th c. on the basis of doctrinal vocabulary and references. Conservatively c. 1200–1265.
