Jingqing Daofu

Jingqing Daofu (鏡清道怤, 868–937) was a Dharma heir of Xuefeng Yicun and one of the principal teachers of the second-generation Xuefeng community in Fujian and Wuyue^[1]. The lamp records describe a master particularly known for using sensory phenomena — the sound of rain, a wind through the trees, a bird's cry — as material for testing students' direct apprehension.

The best-known of his exchanges is preserved as Case 46 of the *Bìyán Lù*: a monk asks, "What is the sound of raindrops?"; Jingqing answers, "*Liú-liú-liú*" (the dripping itself), and presses the student on whether they "themselves are turned by the sound of raindrops" or able to remain undisturbed within it^[2]. The case, with Yuanwu Keqin's commentary, became one of the standard koans of the Song-period Linji curriculum and a paradigmatic Xuefeng-line investigation of the gap between direct sensation and conceptual overlay^[3].
