How very intimate the bodily sense is can be seen by performing a little experiment in your imagination. Think first of swallowing the saliva in your mouth, or do so. Then imagine expectorating it into a tumbler and drinking it! What seemed natural and ‘mine’ suddenly becomes disgusting and alien. Or picture yourself sucking blood from a prick in your finger; then imagine sucking blood from a bandage around your finger! What I perceive as belonging intimately to my body is warm and welcome; what I perceive as separate from my body becomes, in the twinkling of an eye, cold and foreign.
