The Ketsu gonjitsu-ron 決権実論 of Saichō 最澄 is one of the most important texts regarding his debate with Tokuitsu 徳一. The Dengyō daishi zenshū 伝教大師全集 and the Nihon Daizōkyō 日本大蔵経 include the text. But it is well known that the printed editions are not complete since they lack the sixth of the text’s twenty sections.
The Minobu bunko 身延文庫 kindly gave me an oppotunity to read its manuscript. I was able to discover there the missing section in this text and to recognize that this manuscript is the only source so far known which preserves all sections of the work. This paper presents a reprint edition and analysis of the heretofore missing section.
