Full Idea
Proprioception is not focused single-mindedly on the self, but is focused on a number of objects - the component bodily parts that belong to the self. There is no obvious need for a concept of the self, or of indexicality.
Clarification
'Proprioception' is awareness of your own body
Gist of Idea
Prioprioception focuses on your body parts, not on your self, or indexicality
