Where does the mind end and the body begin? This is an interesting question to consider. In Non Duality sometimes 'the mind' refers to the seemingly finite mind, sometimes it refers to Infinite Consciousness. There's no problem with this, as the seemingly finite mind can be considered as the peak of a wave on the ocean of Infinite Consciousness, which could equally be called Infinite Mind or Awareness. When the seemingly finite mind returns to Infinite Consciousness it is clear that it never really left and there never really was a finite mind.
This finite mind seems to get tangled up in identifying with the body, and limits itself accordingly. It's impossible to find where the mind ends and the body begins. The mind controls much of the movement of the body, and the state of the mind affects the emotions and even the physical health of the body. The eyes see the body (except from where they are seeing from) and other senses give a rounded picture of the body. We feel when there is a pain in the body, if the body is thirsty, hungry, tired or weak. All these perceptions and sensations of the body are experienced in the mind. It is the mind that is the centre of perception and sensation for the body. It is in this way that sometimes Non Duality teachers speak of the body-mind.
This understanding of perceptions and sensations appearing in the mind leads to a deeper recognition that the mind and the body aren't really separate. The mind is mistaken in its sense of identity with the body. The body and the world are perceived in the seemingly finite mind. Thoughts are also perceived in the mind, seemingly by the identity or ego. This ego or sense of identity is also witnessed. We witness our sense of identity in the mind. All that the seemingly finite mind perceives is witnessed by a deeper 'collective mind' or shared mind, that is Infinite Consciousness. Ultimately there is no finite mind, body, or world. There is only Infinite Consciousness.
