Zen Koan #16: Joshu’s “Wash Your Bowl”
Zen Koan #16: Joshu’s “Wash Your Bowl”
Full Archive Here.
Context: A newcomer monk named Zhu-yan came to Master Joshu (Zhaozhou). Joshu asked, “Have you eaten your rice porridge?” The monk said, “Yes, I have.” Joshu said, “Then go wash your bowl.” Upon hearing this, the monk was enlightened.1
Commentary: This delightful koan (Gateless Gate #7) shows Joshu’s genius for pointing to the very ordinary as the site of awakening.
The dialogue seems trivial: Joshu is essentially saying, “If you’re done eating, clean up.” But that is exactly why it jolted the monk into realization. After consuming teachings (rice porridge), one must digest and then cleanse – letting go of even the teaching.
“Wash your bowl” is pure activity – straightforward, no-mind engagement in the present task. In that moment, the monk suddenly “got it”: Zen is nothing other than this. He had likely expected Joshu to give some high instruction, but Joshu just gave him a chore.
The young monk’s mind, having eaten up the Dharma, was still “dirty” with subtle conceptual remnants of seeking. Joshu, by saying “Wash your bowl,” effectively told him to empty himself – to start fresh, without clinging to the past meal (past knowledge).
There is also deep symbolism: an empty bowl is a classic image for an open mind. By washing his bowl, the monk emptied and purified his mind-bowl, instantly experiencing enlightenment as the ordinary mind of cleaning up.
Case records say from then on the monk understood the meaning of “everyday life is the Way.” This koan emphasizes simple mindfulness. After enlightenment, there is no fanfare – you still must do the dishes. But the difference is, after Zen insight, washing the bowl is recognized as the miraculous activity of Buddha.
Before enlightenment, chop wood, carry water (or wash bowls). After enlightenment, chop wood, carry water – and wash bowls. Nothing changes, yet everything is different. The monk’s sudden satori shows that when the time is ripe, the smallest trigger can spark awakening. He had likely been straining to “get” Zen – Joshu’s casual instruction allowed his mind to relax and let the truth sink in.
Wumen’s commentary on this koan playfully admonishes students: “Joshu’s eyes see the distressed monk; easily he strips off the monk’s blinders. If you can’t grasp the plain truth here, you’ll wear your bowl on your head for ten thousand years like a ghost.” In other words, don’t overcomplicate Zen – see the direct teaching in Joshu’s words.
Have you eaten? If so, did you truly taste that meal? If yes, then proceed to the next task. Nothing is lacking; nothing is leftover. Now, wash the bowl – which is to say, attend to what’s needed in this moment with full presence. That is Zen in action.
Even today, Zen teachers might simply say “Wash your bowl” to a student who is overthinking or lingering on a past realization. It means: “Finish and let go; move on.”
Ironically, “Wash your bowl” became itself a famous saying (thus, an object of thought for many). But the point is to feel the water, feel the bowl, just wash.
The monk did just that, and he awakened to the choreless chore – where self and bowl and water and washing all merge in thusness. His bowl was clean; his mind was clear. May we all realize such clarity in our daily cleanup.
Zen Koans: The Gateless Gate to Insight
Zen koans are short, paradoxical anecdotes or questions used in Zen Buddhism to provoke deep reflection and awaken insight beyond logical reasoning. A classic koan often features an encounter between a student and a master where the master’s response is unexpected or seemingly nonsensical. Koans are not riddles with trick answers; instead, each koan is a “Gateless Gate” – a barrier that the logical mind cannot pass. Only by dropping analytical thinking and engaging one’s whole being can one penetrate a koan and experience a shift in consciousness. As 18th-century master Hakuin Ekaku described, “From the very beginning all beings are Buddha... It is like water and ice... Stop the movement to grasp or reject and behold: the water flows clear and freely” – a poetic summary of the koan spirit of letting go and directly seeing reality.
Koans emerged within the Chán/Zen tradition of China during the Tang and Song dynasties (7th–13th centuries) and were later transmitted to Japan, Korea, and Vietnam. Koan practice involves contemplating these stories during meditation or daily activities, often under guidance of a teacher. The seemingly illogical responses of the masters are designed to frustrate the discursive mind and force the student to turn inward, smashing conventional dualistic thinking. The great Zen teacher Wumen (Mumon) said one must “pass through the barrier of the ancients” to realize enlightenmentsacred-texts.com. In koan practice, great doubt and great faith work together – as the student’s habitual thinking gets tied in knots, a breakthrough becomes possible.
Classic Collections of Koans
Over generations, Zen teachers compiled koan collections with commentary to aid students. Three of the most famous are The Gateless Gate (Mumonkan), The Blue Cliff Record (Hekiganroku), and The Book of Equanimity (Shōyōroku):
The Gateless Gate – compiled in 1228 by Chinese master Wumen Huikai (Mumon Ekai). It contains 48 koans (plus one added later), each with Wumen’s commentary and verse. The title “Gateless Gate” indicates that the only barriers to enlightenment are our own attachments. Wumen’s cases include famous dialogues like “Joshu’s Dog”, “Mu”, and “Nansen Cuts the Cat”. Wumen’s brief commentaries are often wry or poetic, designed to jolt the reader’s mind into a new perspective.
The Blue Cliff Record – a 12th-century collection of 100 koans, expanded from earlier compilations by master Yuanwu Keqin. The Blue Cliff Record includes extensive commentary and verse for each casebluecliffrecord.ca. These koans are drawn from the golden age of Zen in Tang/Song China and feature many renowned masters. The Blue Cliff is known for its literary elegance and subtle, layered analysis – in fact, it was once suppressed for fear monks would intellectualize its poetry instead of directly realize the truth. Nevertheless, it remains a treasure trove of Zen wisdom, including koans like “Every Day Is a Good Day”, “The Highest Meaning of the Holy Truths” (Bodhidharma’s encounter with Emperor Wu), and Layman Pang’s stories.
The Book of Equanimity – also known as the Book of Serenity, compiled by Wansong Xingxiu in the 12th century. It contains 100 koans (with some overlap with the Blue Cliff) and emphasizes balanced, peaceful reflection – hence “equanimity.” Each case is accompanied by verses by earlier master Hongzhi. The Book of Equanimity includes cases such as “The World Honored One (Buddha) Points to the Ground”, “Jizo’s Most Intimate”, and “Rinzai’s True Person”. It is valued in the Sōtō Zen school for its gentle yet profound approach.
Each of these collections became a classic, studied by monks and lay practitioners alike. In the Rinzai Zen tradition (especially in Japan), a teacher might assign koans sequentially to trainees – starting with a “first barrier” koan like Mu or “What is the sound of one hand?”, then moving through dozens or even hundreds of koans over years of training. In Sōtō Zen, koans are not assigned in the same way, but they still inform teachings and are reflected upon during zazen (sitting meditation) or in daily life stories.
Koans are “alive” – not mere texts to be parsed, but encounters to be experienced anew by each practitioner. There is a saying that “a koan is not answered, it answers you.” In working with koans, one isn’t solving a puzzle so much as allowing the koan to work on one’s own tightly held perspectives. A genuine response to a koan comes not from the intellect but from one’s whole being, often spontaneously. It could manifest as a word, a gesture, a deep bow – or simply a fundamental shift in understanding. The commentaries and verses provided by the classic koan collections are there not to explain the koan’s “solution” (indeed, any such explanation could spoil it), but to point towards the state of mind of the masters and to inspire the adept. They often use allusions, poetry, or humor to hint at the deeper meaning.
Below, we explore 100 traditional Zen koans drawn from the Mumonkan, Blue Cliff Record, Book of Equanimity, and other classic Zen lore. For each koan, we present the original story or exchange (in English translation), give a bit of historical/spiritual context about the teachers or setting, and offer a brief commentary or interpretation to illuminate the key insight or paradox. These koans are not meant to be “understood” in a conventional way – rather, let their images and words resonate beyond reason. As Wumen said in his preface to The Gateless Gate, “If you do not pass the barrier and do not shatter your illusions, you will remain a ghost clinging to bushes and grasses.” But if you step through the gateless gate, even the most ordinary moment – hearing the rain drip, seeing a flower bloom, washing your bowl – can reveal ultimate truth.
One Hundred Zen Koans (with Context and Commentary)
Below is a curated list of 100 classic Zen koans. They span the early Chinese masters (6th–10th century), the golden age of Zen (Tang/Song dynasties), and a few later and modern anecdotes that have entered Zen teaching. Each koan is titled by a distinguishing phrase or subject. The context notes the protagonist master (and era, if known) or source, and the commentary highlights the paradox or insight. Many of these koans appear in the aforementioned collections, indicated in parentheses for reference (GG = Gateless Gate, BCR = Blue Cliff Record, EQ = Book of Equanimity). Whether a koan is encountered in formal practice or casual reading, it can serve as a “finger pointing at the moon” – do not fixate on the finger (the words), but look to the moon (your own direct experience)!
