Pain is a perception to the person experiencing it. What is
perceived as painful to one is not necessarily painful to another. It
is not up to anyone to decide what is painful to another. It would
be passing judgement on another person to assume or say what is going
to be painful for them.

In fact when looking at the eight limbs it brings to mind the fifth
to me.
"Pratyahara, the fifth limb, means withdrawal or sensory
transcendence. It is during this stage that we make the conscious
effort to draw our awareness away from the external world and outside
stimuli."

Just my two cents worth.

BTW I've been a lurker on the board for awhile and enjoy the
discussions very much. I just felt compelled to contribute to this
one.
