Outline of Final Research Achievements

I researched about the process of establishing the main text of Keizan Jokin’s lecture collection Denkoroku by examining its families of manuscripts. The study subject is the manuscript with the oldest main text (the old book group) among the families of manuscripts. In addition to the nine manuscripts I have researched already, four new manuscripts were examined and their main texts were compared and revised. By the state of common ownership of complex and the unique writing style of the main texts, it is revealed that the old book group is classified into four texual transmissions (A, B, C and D). It is understood that these four groups were branched in the process of transcription from the original text. At the same time, by alteration trace uniquely found in the group B, it is suggested that there was no complex or lacuna in the dispersed original text.

Academic Significance and Societal Importance of the Research Achievements

『伝光録』は古写本と流布本では大きく本文が異なっているが、これまでの研究においては、いずれの本文が信頼できるものであるのかという点に注意が払われることは稀であった。本研究においては、古形を保持した『伝光録』の写本群を網羅的に比較対照し、系統立てを行うことで、もっとも成立当初に近い本文が、いずれの写本に記載されているのかを明らかにした。本研究により、信頼性の高い本文に基づく『伝光録』研究が可能になったという点に学術的意義が求められる。そして、日本中世禅宗における思想の一端が明らかになることは、禅思想に淵源する日本文化の解明に寄与するという社会的意義がある。
