If we look at integrity from this point of view, it would mean being true to your beliefs and principles, or as the definition above states, steadfastly adhering to the high moral principles or standards that you have set for yourself to follow.

This is what integrity means to the true warrior who seeks to live the warrior lifestyle. Without integrity, it is impossible to truly live the warrior lifestyle because the principles of the warrior lifestyle are not mere suggestions which one follows when he is in the mood, and sets aside when they become inconvenient or problematic.

The true warrior must first decide that he is going to live according to the principles, which he has committed himself to, and make them the code by which he will live his life.
