In feudal Japan bushido ("the way of the warrior") was the code of moral principles which the samurai were required or instructed to observe. It is a code unuttered and unwritten; an organic growth of decades and centuries of military career. In order to become a samurai this code had to be mastered.
The seven virtues are loyalty, courage, compassion, respect, honesty, honour, and integrity. As you can see these are not only good for a samurai, but for those of any profession or hobby. Even geocachers!
