Koan training uses a short, often rationally opaque phrase as an object of meditation rather than a puzzle to solve. A practitioner with a steady meditation base sits patiently with the koan, sometimes repeating its central sound or phrase with each breath until it permeates the practice. The koan can challenge the deep assumption that the self is separate from everything outside it and may contribute to an opening or kensho. In teacher-guided training, the practitioner then meets an experienced teacher who asks checking questions. The responses both test whether the experience is direct and help the practitioner explore it more deeply. Continued work across further koans aims to integrate non-dual insight with ordinary life rather than preserving it as a separate, extraordinary state.
Origin
Henry Shukman described a classical Zen training system rooted in Chinese Chan records and illustrated it with his own work on the koan Mu.
Core principles
- 01Approach a koan through meditation rather than rational puzzle-solving
- 02Let the phrase work on assumptions about a separate self
- 03Use checking questions to test and deepen direct experience
- 04Continue training after an opening instead of treating it as completion
- 05Integrate insight with ordinary life
How to run it
- 1
Build a meditation base
Develop a steady practice and enough familiarity with meditation that sitting is sustainable. Koan work can deepen meditation, but the formal training Henry describes normally rests on an existing practice.
Pro tip Patience and comfort improve the quality of the work.
Watch out Deep koan training is not for everybody.
- 2
Take up a koan
Receive a phrase from a teacher or choose one to sit with. Treat it as an expression of awakened experience, not as a conventional riddle with a clever answer.
Pro tip Use the heart of a longer case rather than trying to hold every line.
Watch out Do not reduce the koan to rational interpretation alone.
- 3
Sit with the phrase
Let the koan remain present during meditation. With Mu, Henry describes softly voicing the sound with each breath until it gently takes over the sitting.
Pro tip The more patiently the phrase is held, the more comfortable the practice can become.
- 4
Allow an opening
Keep practicing without trying to manufacture a predicted event. An opening may reveal a non-dual dimension in which the ordinary boundary between self and world changes decisively.
Pro tip Notice direct experience rather than seeking a conceptual explanation.
Watch out An unusual or destabilizing experience may need appropriate professional support as well as contemplative context.
- 5
Meet through checking questions
Bring the experience to an experienced teacher and respond to probing questions about the koan. The way the practitioner responds helps confirm the shift and provides a shared meeting point.
Pro tip Answer from the experience rather than from memorized language.
- 6
Explore the shift
Use further checking questions and koans to inhabit the new way of experiencing more fully. Let the work reveal how the extraordinary dimension is already present in ordinary experience.
Pro tip Revisiting koans with different teachers can expose deeper layers.
- 7
Integrate ordinary life
Continue training until awakening and daily activity are no longer treated as separate worlds. Apply the resulting balance, clarity, empathy, compassion, and openness in normal responsibilities.
Pro tip Keep work, family, and ordinary activity inside the practice rather than escaping them.
In the wild
Henry sat with Mu during meditation and ordinary activities such as riding his bicycle. While carrying dinner upstairs and watching a comic scene with his family, he experienced a sudden vast emptiness accompanied by gratitude, love, and happiness. Later, his teacher connected the event to Mu and used checking questions to help him recognize what the koan was for.
→ The experience became the starting point for continued koan training rather than an isolated event.
Henry described Yamada Roshi as a serious Zen practitioner who also led Mitsubishi's securities business with roughly 30,000 employees under him. Yamada believed Zen supported rather than impaired his career by improving balance, clarity, empathy, compassion, and openness to other viewpoints.
→ Deep practice remained compatible with demanding ordinary responsibility.
Common mistakes
Solving the koan intellectually
A rational answer leaves the underlying mode of experience unchanged; the practice is designed to work beneath ordinary conceptual problem-solving.
Treating one opening as completion
The ongoing training is meant to clarify, ground, and integrate the experience across ordinary life.
Practicing without needed support
A powerful experience can become frightening or destabilizing without a suitable contemplative container or appropriate clinical help.
Is it for you?
Best for
It is best for experienced meditators drawn to Zen practice and willing to work patiently, often with a qualified teacher.
Not ideal for
It is not ideal as a purely intellectual riddle exercise or as a substitute for psychiatric care during destabilizing experiences.
From the transcript
“you're usually just sort of repeating it softly you sort of add it to your breath meditation”
“the way we respond to them will confirm that we've really experienced this thing”
“they will somehow help us explore it even more deeply”
