The idea of "pure" consciousness without any content seems incoherent. If I have an ability to see but there are literally no visual stimuli to perceive, do I meaningfully have vision, much less "pure" vision? How would I know?
Well. We KNOW that everyday, but we pay no attention due to two assumptions. First, most people (scientists too) take the contents of experience to be consciousness. Second, all experiences are by default internalised under a realism-materialism world view.
We assume that the conscious experience alone constitutes consciousness. But where is the conscious experiencer? We, in dream and in waking state, experience contents of mind-consciousness. We experience ‘I’ as very intimate experience. The rest of the experience becomes a distant ‘world out there’. This problem is further compounded by self reference problem, the 'I' reflecting the 'I' ( like two mirrors reflecting images infinitely). Self reference makes the notion of self overshadow the ‘world’. This, IMO, is the root of notion of realism- materialism: "I am this and there is an objective world out there". We forget that the body-mind-world are all objects to one cognising self, which is not an object of experience.
But truly, consciousness constitutes both the ‘conscious experiencing experiencer’ (self) and the 'experiences of the experiencer' — the contents of the consciousness. The contents change. But the cognising self does not. The cognising self is the common link through all changes because of which discernment of the changing states can happen.
So, I said that there is empirical evidence of consciousness in our everyday life. But we pay no attention to it. Mind goes to sleep in infinite, non dual, time-less, desire-less, and rejuvenating consciousness everyday. But we miss it carelessly.
In deep sleep, there is no duality and no contrast. Subjective experience of this state is of ‘not knowing’.
But deep sleep experience is also an experience — of non dual, homogeneous, timeless, desire-less realm of mind. The deep sleep state seems to be a ‘not knowing’ state because in pure consciousness there is nothing to know. There is no second self, no second sound, no second smell, no second colour .... it is like pure unobstructed light of a car head lamp. Until the light beam encounters an obstruction, it is not perceived. In deep sleep nothing is perceived because nothing has been created yet.
As soon as in the same realm of mind-consciousness, division of subject (I sense) and object (dream world) occurs, space-time comes up. This experience is mental— a mental I and a subtle mental world. In the same empty consciousness of deep sleep, objects get created and as if we become conscious.
On waking up, the mind is experienced as constituted of subjective experience of grosser ‘I’ and grosser world.
The cognising subject and the consciousness links the three states of deep sleep, dream, and waking. The conscious self that sees the states and the transitions persists through the states of sleep, dream, and waking.
So, the deep sleep experience, which seems unconscious to the unthinking ignorant, is actually the experience of pure consciousness devoid of any partition and objects. (
Same deep sleep experiences under full consciousness of a meditator is the experience of the non dual self, which is pure consciousness).
In above note, only the red part is promissory, that one has to subjectively experience through meditation or through entheogen. Rest of the note is everyday experience of everyone, but examined in light of a world view different from that of materialism.
