The Way of the Samurai

From the film, Ghost Dog: The Way of the Samurai

When it rains and we are met by a sudden shower
Why do we run or try to shelter under trees?
Why do we try so hard not to get wet?
If you resolve yourself to the fact that you will get wet
Then you have no reason to get vexed
Even though you will get the same soaking
This understanding extends to everything.

-- Ghost Dog, translation of text from the Hagakure
