If you ponder the many examples of how truth is sacrificed to serve ego, that helps define through a process of elimination what the Way of the Warrior means. Like, how can you be a Warrior in choosing ego over truth? You can't, therefore the Way of the Warrior must include choosing truth over ego as one component.
What got me thinking about this is the observation that too many people are being held hostage by their egos. There is a defense perimeter set up around their ego with trip wires. So long as you stay outside that perimeter, they remain calm and logical, sociable and even courteous. But cross the line by threatening their ego survival, their insecurities, sacred cows, need to feed, or puffed up self-image, and the ego launches into a barrage of logical fallacies, emotional manipulations, and other tactics to recapture the territory.
I think a Warrior would have the awareness, self-honesty, logical integrity, and humility to sacrifice ego on the altar of truth whenever possible. The non-Warrior probably doesn't even recognize the ego, maybe identifies with it, carries out its commands, never questioning its impulses and taking these as their own. Being a Warrior is not about being a skilled and dedicated fighter so much as knowing what to fight in the first place, because even a non-Warrior can be a strong fighter though one who battles for the other side.
