Is Bushido some bullshit warriors made to go to war even more

[charlie cho]

I heard many warriors tend to feel affinity to being spiritual. I can relate to that because being an athlete most of my life, you tend to try to be in state, in the flow in order to remain in the high ground over your opponent. The moment you think a foolish thought, positive or negative, you'll tend to lose the game, and even if you don't lose immediately, you lose in the long run in some alternative way. Did you know Peter Realston was actually a martial artist? Buddha was in a warrior tribe? Muhammad of Islam was a warlord? Often, Krishna attacked a another tribe for some reason. 

This paradox breaks my brain apart. Do you people know any literature written about this paradox?
