This poem can be found in the Tanjing written by Dunhuang. As for the origin of this poem, there is a clear record in the fourth to eighth sections of the Tanjing: Hongren, the fifth ancestor, "called all his disciples one day" and asked everyone to "write a poem". He also said, "If you get the gist", that is, "Fu Yi is as good as the law, which is an important thing for six generations." Shen Xiu, the last disciple of Hong Ren, wrote a poem in front of the door: "I am a bodhi tree, and my heart is like a mirror platform. Wipe it frequently to make it dust-free. " When Hong Ren learned of this, he "summoned the abbot" and said that "if you do this, you won't be in front of you" and "if you find the supreme bodhi, you won't be there", so he asked him to "write another poem". And "it's impossible to show off for a few days." Huineng's poems are aimed at the beautiful "spiced tree". According to the altar sutra, Huineng couldn't read, so she first "asked someone to read" the beautiful melody, and then wrote this song "asked a scholar to write it at the Western Wall".
