While surfing the net the other evening I came across a quote I liked:
"A Soldier is not the same as a Warrior. A Soldier is someone who fights, and may even fight well, but hasn't developed his heart. A true Warrior has suffered and has developed a compassionate heart."
This is a really nice way of differentiating those who just like to fight and are full of bravado and their own ego versus the warrior who is on a path of self-discovery and healing. I could write more but I think the verse says enough.
