In the Fire Book, Shinmen (Miyamato) Musashi describes a technique described as to renew. Musashi states that when fighting with the enemy, sometimes the spirit becomes entangled and there is no possible resolution.

The trick to change the rhythm and win through a different technique without changing our circumstances.
