The case
An old woman had built a small hermitage and supported a monk there for twenty years. To see what he had attained, she instructed a young woman she sent with his meal to embrace him suddenly and ask: "What is this like?" The girl did so. The monk replied: "A withered tree leans against a cold cliff; no warmth remains in the three winters." (枯木倚寒岩，三冬無暖氣) When the girl reported this, the old woman said: "For twenty years I have fed a worthless impostor." She drove him out and burned down the hut.
Why the monk failed
The monk's response sounds impressively Zen. Withered tree. Cold cliff. Three winters no warmth. Classical Chinese poetry of non-attachment. Many Western practitioners reading this case first assume the monk gave the right answer and the old woman was being unreasonable. The old woman's test is more precise than it appears. She is not testing whether the monk can avoid acting on sensual impulse — she is testing whether the contact registers as alive or whether he has insulated himself from all contact as a defensive strategy. The "withered tree" response demonstrates insulation, not realization. A corpse would have given the same response. The monk has achieved a state that is indistinguishable from emotional deadness, and has confused this with awakening. The old woman, who has lived closer to actual life than the monk has for twenty years, recognizes the difference instantly.
What would have been a right response?
The case does not tell us. This is deliberate. Any formulaic "correct answer" would reinstall the technique the monk was using. The right response would have been: whatever arose authentically in the moment of contact, received in presence, without either acting on impulse or fleeing into ascetic imagery. The Rinzai tradition in later centuries offered demonstrations — not as "the answer" but as examples of what alive response looks like. Some: simply meeting the girl's eyes steadily. A quiet, present question about why she was there. A laugh that neither rejects nor grasps. None are "the answer"; all are living where the monk was dead. What the case ensures is that nobody reading it can pass the test by memorizing a reply. The test is of the practitioner's state, not their repertoire.
Why this kōan specifically hurts Western practitioners
A large portion of Western Zen in the 20th–21st century has been shaped by men who left intense relational lives to pursue contemplative practice. Many arrived at states that looked like equanimity but were partially disengagement from the relational demands that had been experienced as crushing. This is the "dismissive-avoidant" pattern the contemporary attachment literature names (see the attachment-style-practice-relationship article). The old woman's test is specifically calibrated for this pattern. She is not testing whether the monk can be alone; she is testing whether he can meet contact when it arrives. Her burning of the hut is ruthless because the pattern is widespread and tends to be self-protecting. For any practitioner who has a long practice history but notices that their actual relationships remain thin, distant, or performatively "non-attached," this kōan is the one to sit with.
Working with the case
Do not treat it as a riddle. Sit with it until it touches a specific place in your own practice: - Do I feel more comfortable in formal practice than in the messy particularity of actual relationships? - Do I notice myself using Buddhist vocabulary ("non-attachment," "equanimity," "just being present") in moments that also happen to protect me from relational contact? - If I were in the monk's place today, is the "withered tree" response something I would feel accomplished for producing? If any of these land, the old woman is looking at you. This is not condemnation — it is the case doing its actual pedagogical work. Real realization includes being alive in contact. Anything short of that is the hut about to burn.
