Hagakure.

J'ai récuperé le bouquin, donc je peux vous donner quelques citations...

"There is something to be learned from a rainstorm. When meeting with a sudden shower, you try not to get wet and run quickly along the road. But doing such things as passing under eaves of houses, you still get wet. When you are resolved from the beginning, you will not be perplexed, though you still get the same soaking. This understanding extends to everything."

"A person who knows but a little will put on an air of knowledge. this is a matter of inexperience.When someone knows something well, it will not be seen in his manner. This person is genteel."

"People who have an intelligent appearance will not be outstanding even if they do something good, and if they do something normal, people will think them lacking. But if a person who is thought of as having a gentle disposition does even a slightly good thing, he will be praised by people."

Et enfin un dernière que je trouve très drôle...

"Matsudaira no kami said to Master Mizuno Kenmotsu
"You're such a useful person, it's a shame you're so short."
Kenmotsu replied,
"That's true. Sometimes things in this world don't got the way we would like. Now if I were to cut off your head and attach it to the bottom of my feet, I would be taller. But that's something that couldn't be done."
