Kuji-kiri

Kuji-kiri is a special technique that some people in Japan use to focus their mind and body. It involves using your fingers to make certain patterns, almost like making a secret code with your hands.

People who learn how to do kuji-kiri usually do it as a part of a martial art training. It's like a special skill they can use to help them be stronger and more focused.

Each pattern made by the fingers has a special meaning, like "protection" or "energy." And when you make these patterns while focusing your mind, you can feel very powerful and calm.

Some people even believe that kuji-kiri has magical powers, but it's really just a way to train your mind and body to work together in a special way.
