subject to any variation through any corporal either pain
or pleasure, neither suffer it to be mixed with these, but let
it both circumscribe itself, and confine those affections
to their own proper parts and members. But if at any time
they do reflect and rebound upon the mind and understanding
(as in an united and compacted body it must needs;) then must
thou not go about to resist sense and feeling, it being natural.
However let not thy understanding to this natural sense
and feeling, which whether unto our flesh pleasant or painful,
is unto us nothing properly, add an opinion of either good
or bad and all is well.
