Query: Warrior ethics never change!

It is amazing to me that such a small book can cover so many deep and life changing principles. This is not just a code of conduct for warriors it really should apply to all people. The concepts of loyalty, bravery, and honor are brought out and explained in a clear straightforward manner. I really enjoyed reading this book though I have never trained in martial arts or studied anything about the samurai. I became interested because of our American warriors overseas and decided to give this a read. I am blown away that all the same principles apply to warriors today as several hundred years ago.
