詔天台教部入大藏流行。初天竺寺僧思悟求教藏流行。自乙丑春禱於大悲觀音。至是行願克遂。乃焚身于日觀庵前。用報佛恩（天竺別集）。

An imperial edict ordered that the Tiantai doctrinal division be entered into the Great Canon for dissemination. Earlier, the monk Siwu of Tianzhu Monastery sought to have the doctrinal canon disseminated; from the spring of the yichou year, he prayed to the Great Compassionate Guanyin, and up to this point his vow was fulfilled. He then burned his body in front of the Riguan Hermitage to repay the Buddha's kindness (Tianzhu bieji).
