Proprioception is the sense by which we feel our internal sensations, specifically our muscular sensations. It is how we sense ourselves from the first person, as opposed to how others perceive us from the third person. In CSE, we refer to this inner awareness as our “soma”. The soma is our own body, and how we experience ourselves from the inside.
When we perform Somatic explorations, closing our eyes helps us fine tune our proprioceptive awareness. Opening the eyes to observe where we are in space places us in a third person position outside of ourselves, and outside our proprioception.
