Anything you can discover or propose as an attribute of consciousness, whether innate or developed by practise cannot be what characterises it. Whether it is continuous or granular, reflexive or pre-reflecive, spatial or punctual etc., all of these correspond to possible experiences and as such are inessential. Consciousness is what experiences, or it would be if the phrase still made sense when pushed to its utmost limits, but that we are permitted to speak of it only reflects a very limited and localised result, an effect and not a cause. From your perspective it like a tiny aperture, empty and dark itself, through which illumination of functioning flows; for you being is what is perceived and that means that the perceiving has no being in itself. Your nature constrains you to understand being in this completely inverted way. You are ignorant to the precise degree that you believe that there can be more than one consciousness - it is that simple.
