„In our modern world, we look unkindly on mistakes and imperfection. But this is far from the samurai ideal. Mistakes are part of the learning process and if you haven't made them then you are, indeed, dangerous because it means you have never learned anything. Mistakes, to a samurai, are the proof of your learning.“
— Alexei Maxim Russell Canadian writer 1976
from Instruction Manual for the 21st Century Samurai.
