Qīngzūn 清澊 (Jp. Seijun, age 34 with 20 years’ monastic seniority in 1468) was a Muromachi-period Tendai monk at the Jōrinbō 常林房 who copied 源信 Genshin’s Jùshě Lùn Sòngshū Zhèngwén (KR6l0043, T2253) in 1468; his manuscript is one of the principal witnesses in the chain that led to the Taishō edition of the text.
