With consciousness the problem is that it's not defined. Neither are terms like mind, intelligence, perception, emotion, affection, thought, God and so on defined.

Then someone can talk addressing many different things using the same terms.

What 'consciousness' are we talking about?

If we mean the self consciousness we experience in the fragmentary perception of thought (C), every one can really find out it is a product of thought, a kind of a trick used by thought to create an illusion of something stable and solid to continue.

What really is is an undivided movement.

If we try Unitary Perception (B) (being aware of everything perceptible, all energy, 'inside' and 'outside' at the same time, without effort), the self consciousness can disappear.

It disappears together with the multitude of problems which are its superproducts like fear or sorrow.
