Johu asked two hermits: What's up? Both raised a fist.
Joshu said: "Schallow water!" to the first, "Fully enlightened!"to the other."
(The Koan-answer is the picture's caption!)
Raise your fist.
An explanation of the Koan answer
That's a very traditional Koan. The same action twice, but each is judged fundamentally differently. One action shows stupidity, the other enlightenment. As there no dualities, stupidity an enlightenment are just the same. Joshu tries to trick you.
The background story of this Koan
In medieval times Buddhist-masters were regarded, and used, as magicians. They lived in the forests as isolated hermits. Some roamed the countryside, teaching their students while wandering around.
The story of the Koan seems simple but quite surprising.
Joshu went to a place where a monk had retired to meditate and asked him: "What is, is what?"
The monk raised his fist.
Joshu replied: "Ships cannot remain where the water is too shallow." And he left.
A few days later Joshu went again to visit the monk and asked the same question.
The monk answered the same way.
Joshu said: "Well given, well taken, well killed, well saved." And he bowed to the monk.
By finding this subtle difference, Joshu shows magical power, it seems.
The original Chinese Goang
Zhaozhou went to the place of one hermitage master and asked, "Exist? Exist?" (or: “Have? Have?”)
The master raised a firm fist.
Zhou said, "Shallow water is not the place to anchor a ship." Then he walked on.
Again he went to the place of one hermitage master and said, "Exist? Exist?"
The master also raised a firm fist.
Zhou said, "Able to let go, able to seize, able to kill, able to let live," then he made the proprieties.
Traditional Commentaries and .... Poems (Gata)
The raised fist was the same both times.
Why is it Joshu did not admit the first and approved the second one? Where is the fault?
Whoever answers this knows that Joshu's tongue has no bone so he can use it freely.
Yet perhaps Joshu is wrong. Or, through that monk, he may have discovered his mistake.
If anyone thinks that the one's insight exceeds the other's, he has no eyes.
The same raised firm fists; for what purpose was one approved and one not approved? Just say, in which place were all the errors?
If from within you are able to issue one turning word, then you see Zhaohou’s tongue is boneless and very naturally it is able to rise up to help put in place or turn upside down.
Although, on the other hand, it is like the struggle affects Zhaozhou who retreats because of being destroyed by the two hermitage masters’ investigation.
If you say the two hermitage masters existed as superior and inferior you do not possess the eye of the three studies. If you say they were not existing as superior and inferior, you also do not possess the eye of three studies.
The light of the eyes is as a comet,
And Zen's activity is as lightning.
The sword that kills the man
Is the sword that saves the man.
Eye -- shooting star,
Function -- snatching lighting;
To kill a person -- a blade,
To keep a person alive -- a sword.
