Interface with the illusion

There are moments when there is a clear sense of the separation from the "reality". Visual impressions seem to appear like projections in the inside of the head. Increaingly it appears that sensation is the key. Sensation without imagery. Imagery, it appears is the biggest villian and the biggest barrier to the understanding and "seeing". Consistent sensation seem to help to keep the images away - but it is so fascinating to see that without imagery the brain seem to have difficulty experiencing. Even in a massage, I see that the sensation of one's feet being massaged cannot be separated the image of the feet being massaged. Just experiencing the pure sensation of the massage seem so difficult. But once that barrier is crossed, sensation then opens up a new relationship to the reality around. The relationship with the body then becomes the sensation. I sometimes sense that this relationship with the body is really a small spot in the brain and the rest is made up of imagery.
Nisargadatta talks about a practice that we just have to belive that we are not the body. Gurdjieff says that we must use the imagination to intially practice that the reality is that I am. Stephen Jourdain says "The Central rivet of the hallucination is nothing other than the absolute belief in myself in the act of producing a thought of dreaming this or that. ….if people corrected the way they situate themselves they would eliminate 98% of their problems. Then they would be in the zenith of their dream and close to bursting it".
Then Dzogchen texts mentions - "But then, one might ask, how does samsara arise? How does one enter the dualistic vision that is the cause of transmigrations? If, at the moment the energy of the base manifests, one does not consider it something other oneself and one recognizes one's own state as the indivisibility of essence, nature and potentiallity of energy, the movement of energy self-liberates...understanding the essence that is the very nature of primordial enlightenment".

So it appears that the practice is to constantly plug into being in this space of sensation in the heart where one is constantly reiterating to oneself the "unreality" of things around us - visual, thoughts, emotions.
