Osho talks on "koan"
Zen has a special method of meditation. They call it koan or
'ko-an'. A koan is a puzzle. But it is not like an ordinary puzzle.
It is a puzzle that cannot be solved. Ordinary puzzles can be
solved, they are meant to be solved. They may be difficult,
but they are not impossible. A koan is an
impossible puzzle. You cannot solve it; there
is no way to solve it.

For example, this is a Zen koan:
what is the
sound of one hand clapping?
If you use two
hands a sound is created, but if you use only
one hand, what sound is created?

This is a koan. Impossible to solve.
Whatsoever you say will be wrong. Unless
you remain totally silent, everything will be
wrong. This koan is to create a total silence
in you, where no answer is coming.
If answers are coming they will go on being
the wrong answers, because every answer
is wrong – no sound can be created by one
hand...

gong an
(pronounce it "gohng ahn")





The more commonly known Japanese
pronunciation of this Chinese
double-character Zen word is
"koan".

It was developed in Chinese Zen
monasteries in the "classical" period of
Zen, in the 800s CE. This term
originally meant "public case", a kind
of legal term in China, and was used
subsequently by the Zen masters to
identify their "answerless" one-line
questions, as a major Zen meditation
technique.

Examples are:

What is the sound of one hand
clapping?

Why did Bodhidharma come from the
West to China?

Does a dog have the Buddha nature?

What is your original face before you
were born?
