（二十二　丙寅）　天聖四年賜天台教部入藏。天竺寺思悟侍者。焚軀為報國恩。悟錢唐人。初慈雲式公欲以智者教卷求入藏。文穆王公將聞之朝。悟曰。非常事也。小子將助之矣。乃繪大悲像呪以誓曰。事集焚軀報國。會公薨。悟誦呪益精。是年得旨克遂初志（式為贊刻石焉）。

(22. Bingyin) In the fourth year of Tiansheng, the Tiantai doctrinal section was granted entry into the Tripiṭaka. Attendant Siwu of Tianzhu Temple burned his body to repay the grace of the state. Wu was a native of Qiantang. Earlier, Master Shi of Ciyun wished to request the entry of Master Zhiyi's doctrinal scrolls into the Tripiṭaka. Lord Wang Wenmu was about to report it to the court. Wu said, "This is an extraordinary matter; this humble one will assist in it." Thereupon he painted an image of the Great Compassionate One, recited dhāraṇīs, and made a vow, saying, "When the matter is accomplished, I will burn my body to repay the state." Lord [Wang] passed away, and Wu recited the dhāraṇī with even greater diligence. In this year, the imperial decree was obtained and his initial aspiration was fulfilled (Shi composed a eulogy and carved it on stone).
