Tsukamoto gives a series of reasons for which he is unwilling to accept as genuine the Jiumoluoshi fashi lei 鳩摩羅什法師誄, ascribed to Sengzhao 僧肇 and preserved in Daoxuan's 道宣 Guang hong ming ji 廣弘明集: it is missing from early accounts of Sengzhao's writings; the information it provides conflicts with that in earlier sources, and such sources as LDSBJ, GSZ, Jizang and KYL (Zhisheng), etc.
