Song of the Precious Mirror Samadhi


The Song of the Precious Mirror Samadhi is a Zen poem in Classical Chinese that appeared during the Song Dynasty. The work is often attributed to Dongshan Liangjie, the co-founder of the Caodong/Sōtō branch of Zen Buddhism, although modern research suggests this is unlikely.

Dating and attribution

The poem is first mentioned in Juefan Huihong's biographical compilation of 1119, the Chanlin sengbao zhuan, written over 200 years after Dongshan Liangjie's death. Huihong, however, does not attribute the poem to Dongshan. He writes instead that the poem was given to Dongshan by his teacher, Yunyan Tansheng. Huihong further speculates that Yunyan's teacher, Yaoshan Weiyan, probably entrusted it to him in turn. Huihong relates that he came upon the poem in 1108, when it was given to a scholar Zhu Yan by a monk, whom he does not identify. The scholar Morten Schlütter notes that the poem's provenance is doubtful given the way it came to Huihong, and furthermore the style differs substantially from works of the era that Huihong attributes it to. Most later historical sources, such as the Zengaku daijiten, the Bussho kaisetsu daijiten, and Shinsan zenseki mokuroku, attribute the poem to Dongshan Liangjie rather than Yunyan, although again, neither is likely to be the true author.
