What is pain?

Is it the bodies way of saying something in wrong? Or is it the mind becoming overstressed? Is there a way through intense meditation to make pain signals feel good, kind of like altering your own mind? What is pain?

its when you do something that youre not supposed to and then your brain says hey retard youre not supposed to do this and then you say ow and stop. its that simple.

to answer your other question- can you make pain feel good?
if you are constantly exposed to that which causes pain you can build up a tolerance of sorts. but you would have to talk to a masochist to get their point of view on pain becoming pleasurable.
I know from experience that minor pains can be worked around and to a degree- ignored somewhat, but I do not find the sensation of pain to be a pleasurable experience.

My coach once told me "Pain is WEAKNESS leaving the BODY"

Hope thats helpful, :P
