Biographical sketch
Zhàozhōu was born in Shandong. He became a monk young and studied with Nánquán Pǔyuàn (748–835) — the master of the cat-killing kōan. Nánquán was himself a student of Mǎzǔ Dàoyī, whose line represents the mainstream Chinese Chán of the era. Zhàozhōu's first awakening happened with Nánquán. He then wandered for decades, testing his understanding with other masters, and finally settled at a small temple in Zhao province (hence his name, which refers to the location rather than a personal name) around age 80. He taught from approximately 858 to his death in 897, living to roughly 120 years by traditional count. The preserved Zhàozhōu yǔlù (趙州語錄, "Recorded Sayings of Zhàozhōu") contains hundreds of dialogues from this teaching period.
The "ordinary speech" method
A representative exchange (Wúménguān Case 7): A monk said to Zhàozhōu: "I have just entered the monastery. Please give me some instruction." Zhàozhōu: "Have you eaten your rice gruel yet?" Monk: "Yes, I have." Zhàozhōu: "Then go wash your bowl." Another (Case 37): "Why did Bodhidharma come from the West?" Zhàozhōu: "The cypress tree in the garden." These are his method. The monk arrives with a spiritual question. Zhàozhōu answers in the register of domestic practicality. "Have you eaten? Then wash your bowl." "Why did Bodhidharma come?" "See the cypress tree." The answers look wrong because they don't operate at the monk's level of abstraction. But they are exact. Wash-your-bowl is the direct instruction: the essential work is right here, in the rice bowl that is still waiting to be washed after breakfast. The cypress tree is the pointing: Bodhidharma brought no special thing from the West; there is only this tree, right here, and if you can see it clearly you have what Bodhidharma brought.
Why the plainness works
Practitioners arrive at a teacher expecting profundity. This expectation is itself the obstacle: it reaches past ordinary experience toward something elevated, and the elevation-direction is wrong. Línjì's shout defeats the expectation through intensity. Déshān's staff defeats it through physical interruption. Zhàozhōu's ordinary speech defeats it through precise denial of elevated register. The monk asking "please give me some instruction" is asking for profundity in the form of teaching. Zhàozhōu refuses to provide the register. The answer about the rice bowl is not deflection; it is the actual instruction. Practice is exactly this: the bowl that needs washing, the clothes that need folding, the task that is present right now. There is no other practice. But this only lands if the monk has come to the point where Zhàozhōu's plain answer can be recognized as answer. Most monks leave the exchange thinking Zhàozhōu didn't understand the question. A rare few — those ready — recognize the answer and wash their bowl differently afterward.
The most famous Zhàozhōu kōans
**Mu (Wú) — does a dog have Buddha-nature? — treated in the zhaozhou-dog-no article** **Wash your bowl (Case 7, Mumonkan)** — see above **The cypress tree (Case 37, Mumonkan)** — see above **A cup of tea (not in Mumonkan but in the Zhàozhōu yǔlù)** — Two monks visit Zhàozhōu. He asks the first: "Have you been here before?" The monk says yes. "Have a cup of tea." He asks the second: "Have you been here before?" The monk says no. "Have a cup of tea." The head monk later asks: "Master, why do you give both 'have a cup of tea' — whether they've been before or not?" Zhàozhōu calls his name. "Yes?" "Have a cup of tea." **The stone bridge (Case 52, Book of Serenity)** — A monk says: "I've long heard of Zhàozhōu's stone bridge. Now that I've come here, I only see a simple log bridge." Zhàozhōu: "You see only the log bridge; you don't see the stone bridge." Monk: "What is the stone bridge?" Zhàozhōu: "Donkeys cross, horses cross." Each of these operates in the same register: domestic, immediate, denying elevation while somehow pointing exactly where the practice is.
Why Zhàozhōu produced more kōans than any other master
Simple math: he taught for 40 years (roughly age 80 to 120), and the ordinary-speech method produced a high volume of usable teaching exchanges. Shorter teaching careers and more dramatic methods produce fewer, more concentrated events. But there's a structural reason too. Zhàozhōu's plain style translates into written kōan unusually well. A Línjì shout or a Déshān staff blow is hard to render on the page — the physical component is lost. Zhàozhōu's exchanges are nearly all verbal, and the verbal form preserves the full teaching when written down. This is partly why later kōan collections are Zhàozhōu-heavy. His method was preservation-friendly. The Mumonkan has 48 cases; Zhàozhōu is directly featured in roughly a quarter. The Book of Serenity similarly.
