This research is based on a manuscript of the Rokunai Gosho 録内御書 that has been newly discovered in the Ryūkoku University Library. This manuscript is currently composed of 33 volumes, including 117 Gosho writings. The person who transcribed and possessed it is unclear, and the reason that it is now kept at Ryūkoku University is unknown as well. Through comparision with other manuscripts of the Rokunai Gosho, from the perspectives of differences in the primary Gosho texts as well as other characteristics, I found that this manuscript seems similar to those possessed by Hompōji 本法寺, Hayashi Nissho 林日邵, and Nikkyōken 日教研.
When I delivered the above result, I suggested that the study of the manuscripts of the Rokunai Gosho should include this manuscript, as well as the other 20 existing manuscripts.
