Zen Stories or Koans are short tales designed to open the mind to new ways of thinking. They often do not follow what we would consider rational thought, but that’s the point. By removing yourself from what you would call normal or rational, you can see the world from a new perspective.
Here are a few shorter proverbs as well as some links at the end to longer stories:
Do not speak unless it improves on silence
After enlightenment, the laundry.
When walking, walk. When eating, eat.
Those who know don’t tell and those who tell don’t know.
