Is cognition, mind contact or consciousness restricted to internal contacts? Why?
Is eye consciousness limited to internal relationships such as the eye perceptions of the bodily eye or can cognition make more direct contacts beyond internal mind qualities and the body's sense perceptions? Is external contact limited to and always meditated by the body senses?
The perception of external objects is often said to be limited to mediation via the body senses but is this so? Can consciousness operate externally beyond the body and the senses? Cannot consciousness also arise through contact with what is external to the body and it's senses as contact causing mind consciousness, etc., etc., eye consciousness apart from the body and the senses of the body?
I don't understand the doctrinal basis for the commonly expressed thinking that cognitive contact is restricted to mediated sensory contact with what is external via the senses of the individuated body. I don't see why eye consciousness, ear consciousness, etc. should be considered restricted to a relationship with the body senses.
I would like to see a presentation of clear supporting statements in the Tipitaka, etc. for the thinking that mind is restricted in it's contacts to only a single continuum of dependently interrelated bodily forms, sense consciousness meditated via the body senses and directly related ongoing proximate mental qualities. In my understanding this is quite distinct thinking from that describing consciousness as restricted to contact with conditions both internally and externally which are anicca, dhukkha and anatta.
It is my perception that a mind may demonstrate the faculty to contact the external apart from meditation by the five senses of the body. How else but by such contact could mind have direct knowledge of another mind, etc., as variously depicted in the suttas, etc.. I do think that, for the duration of life, mind in a human being persists in dependence upon the bodily form but I do not perceive that consciousness is bound by that form. Much like the relationship between an occupant and a house, conscious contact or clinging may abide internally or it may wander externally. There is an intimate conditional interdependence of mind and body for the maintenance of human life but it is not an absolute imprisonment of the consciousness within it's own mental qualities, bodily forms and senses.
Feel free to disagree or to correct any misapprehension with sound doctrine to the contrary.
