Attached to the idea of "this is what a warrior is" is attached to the idea of "this is what a warrior is!"
When feeling pain, why not realize "This body is feeling pain?" When hungry, why not realize "This body feels hungry?"
Yeah, it doesnt come across as zen and not totally detachment. The reason is, cause says the warrior still goes and looks for food if there's hunger, but not because he's hungry?
I think its totally extreme. I do accept Kris's answer on detachment, that this may have been the intent, but, if a warrior isnt in pain, in the first place, why bother looking for a remedy for pain? And if isnt hungry, why go look for food?
I did wonder tho if some of the expression wasnt really about bodily pain, or physical hunger, but more like pain and hunger for the soul, 'wanting' something, you know?
