Daichi

(1290–1366) was a Japanese Sōtō Zen monk famous for his Buddhist poetry who lived during the late Kamakura period and early Muromachi period. According to Steven Heine, a Buddhist studies professor, "Daichi is unique in being considered one of the great medieval Zen poets during an era when Rinzai monks, who were mainly located in Kyoto or Kamakura, clearly dominated the composition of verse." Upon returning to Japan, he received dharma transmission under Keizan's disciple Meihō Sotetsu. He is considered to be part of the Wanshi-ha poetry movement based on the writing style of the Sōtō monk-poet Hongzhi Zhengjue. While in China, Daichi studied under the poet Gulin Qingmao .

His kanbun poetry often praises the teaching of Eihei Dōgen, especially Dōgen's Shōbōgenzō. For example, when he was able to obtain a copy of the Shōbōgenzō despite living in Kyushu, hundreds of kilometers from Dōgen's home temple Eiheiji, he wrote, Quote|text=The enlightened mind expressed in The Treasury of the True Dharma Eye,Teaches us the innermost thought of the past sixty Zen ancestors.A mythical path stemming from Eiheiji Zen temple reaches my remote village,Where I see anew an ethereal mist rising from among remarkable shoots.

On Practicing Throughout The Day is one of the few pieces of writing by Daichi Sokei available in full in English. In it, Daichi lays out instructions for lay people to practice with monks, giving details on how to behave during each hour of the day. According to Shōhaku Okumura, a translator of the text and a Sōtō Zen priest himself, Sokei stresses the importance of maintaining concentration in each moment of the day, which he equates with awakening itself. For example, Sokei, writes, "When you have breakfast, just attend fully to the gruel with both body and mind...This is called clarifying the time of gruel and realizing the mind of gruel. At this time, you have a pure realization of the mind of the buddha-ancestors" In Okumura's footnotes on the text, he writes, "Each activity [that Sokei describes] is not a step, means, or preparation for other things; rather each step should be completed in the moment."
