佛祖統紀 28.66

28.66

潭州黃打鐵每用工時。常念佛不絕。一日無病。託隣人書偈云。日夜丁丁當當久鍊成鋼。太平將近。我往西方。即座而化。

Blacksmith Huang of Tanzhou, whenever working, constantly recited the Buddha's name without ceasing. One day, without illness, he asked a neighbor to write a verse: 'Day and night, ding-ding dang-dang, / Refined for so long, it has become steel. / Great peace is drawing near; / I am going to the West.' He was then transformed upon his seat.
