c. What is the blown-hair sword?

“A Silver Bowl Piled with Snow” is Case 13 of the Blue Cliff Record. “The Blown Hair Sword” is Case 100. In Case 13, Baling actually asked, “What is Kanadeva’s school?” referring to Kanadeva who was the 15th Ancestor of Indian Buddhism. Here, the School of Kanadeva just means Chan or Zen. Swords were tested for sharpness by blowing a hair across them. If the hair fell in two the sword was sharp.
These three questions and answers are listed in the Commentary to Case 13 of the Blue Cliff Record. Baling studied with the grand master Yunmen, and when you had an awakening, it was the custom to present a poem to the teacher. Baling was nicknamed “The Mouth” for his eloquence. Instead of a poem, he offered these three koans to his teacher. Yunmen responded, “On the anniversary of my death, just recite these three turning words, and you will have repaid my kindness in full.” After Yunmen died, Baling used these koans as a memorial service each year.
