"Water is the source of wisdom; swimming is the mother of all the arts…. Swimming teaches us to live properly. There is no way a solitary swimmer can impose his or her selfish will on the water. Swimming against the current will ultimately result in disaster. Swim with the flow without strain, resistance, confusion, or unnatural movement."
—from the Shinden School, which taught samurai suijutsu, the art of combative swimming
