Itʼs like Superintendent Ce; he had been staying in Fayanʼs congregation but had never asked for personal instruction. One day Fayan asked him, "Why haven't you come for an interview?" Ce replied, "Didn't you know I had an initiatory experience at Qinglinʼs place?" Fayan said, "Tell me about it." Ce said, "I asked, 'What is the Buddha?' Qinglin said, 'The fire god comes looking for fire.' " Fayan said, "Good words, but I'm afraid you misunderstood. Can you say something more?" Ce said, "The fire god is in the province of fire; he is seeking fire with fire. Likewise, I am a Buddha, yet I went on searching for a Buddha." Fayan said, "Sure enough, you have misunderstood." Ce left in a huff and went away. Fayan said, "This man can be saved if he comes back; if he doesn't return, he can't be saved." On the road, Ce thought to himself, "He is the teacher of five hundred people; how could he deceive me?" So he turned back and again called on Fayen, who told him, "Just ask me and I'll answer you." Thereupon Ce asked, "What is Buddha?" Fayen said, "The fire god comes looking for fire." At these words Ce was greatly enlightened.
