Ancient Zen Koans from China



Most Zen Koans were written or collected in 13th to 15th century China.
But there are much earlier Koans too. They train creative, intuitive problem solving.

Sounds strange for people normally use their rational thinking to solve a problem.
But in Zen only an intuitive, creative solution of Koans is accepted.

If you want to find out about this "dogma" in Zen go to the Person that calls itself 'I'

There are six types of ancient Zen riddles or Koans. Their answers are normally hidden but here they are provided.

All riddles show, that the Koan-questions and their answers are not logically connected.
The typical Zen-solution needs intuition and creativity, not logic and intellect.
That what's the ancient Zen Koans demonstrate over and over again.

(To give the answer for a Koan is against the tradition, but it avoids useless mental movements in circles.)
