Could have a lot of fun with this thread, but the deep rooted history of the "Samurai" and ancient warriors can offer a lot. I have read many books on the subject, (The Book of Five Rings, Hagakure, etc.). All were true artists in the art of killing, and yes, along with that, most excelled in a "soft art", (painting, poetry, instruments), just to name a few.
The focus and discipline in their training and lifestyle was extreme, to say the least. Most "true warriors" were seen as outcasts and lived very lonely lives. The ultimate goal through very unorthodox training in austere conditions was to aquire
mushin , or "no mind".
WARNING: Great subject; I could go on for a while.
FYI: "The Book of Five Rings", used to be required reading for Japanese business men, (not sure anymore??). It's all about strategy, and contains 5 chapters-in a certain order; Earth, Water, Fire, Wind, and Void. The lessons learned in this translation can be used from the office to the battlefield, and in everyday life. Great to keep in your personal library for reference purposes.
Great thread! Thanks for allowing me in!!
