Sennin no Uro and Fuka (Legendary Wizard's Go game)

The word of Uro is originated in U (a crow) and Ro (a white egret).
These two birds are related to a black stone and a white stone of Go game. Two legendary wizards are playing the game of Go and a wood cutter carrying an ax on his back is interested in watching the game from the outside.
A long time has been passed.
When a wood cutter came to notice it, his wooden handle of an ax had been spoiled.
A legendary Wizard's life is quite long and it differs from human beings. 
This story suggests us how to spend a life significantly andif we neglect our works a life will be collapsed.
When hooking with things long, we forget ourselves.
Without worrying about the trifles and do always have generous feeling in our life.
