Isn't the OP "Who Am I? Again"...still a question in point ?
I think that we are a mix of all that Stuff that's on the Earth already.
Yes. It is still the question.
It is you (the self) that has experience of three states: waking, dreaming, sleeping. In these three states, 'xyz' (the composite of objects) differ. But do you, the "I" also change? The materialistic view is that only the waking state is reality. And the brain, which is an object of the waking state, is creating the consciousness and dream and sleep states and is also the knower of these states.
The brain that is a waking state object is supposed to be the subject also? Then who it is that is seeing the brain? Is it not foolishness?
Some think that `I Am` is created by `Gods`, not really self evolved.
Is "I am" created or evolved? I do not see that. "I am", as I understand, is unborn pure awareness. In a sense, it is the God.
Because our awareness is never of pure "I am", it is difficult to perceive it. It cannot be perceived as an object, since it is the subject. We cannot easily comprehend pure consciousness because in us consciousness works through layers of memories and attributes. But we can build a couple of thought experiments to help us intuit it. I have borrowed the first thought experiment from Salvadore Poe.
Sensing vs. Knowing - Excerpt from The Way of Freedom • Salvadore Poe
Suppose you are floating in a hermetically sealed, pitch black, soundproof, anti-gravity chamber, so that you have no tactile sensations, no sounds, no sights, no smell and no taste. In this situation, none of the five senses would sense any objects at all. Nevertheless, you would still know the felt sense of I Am. The knowing would know the object, the felt sense of I Am. Knowing needs none of the senses. It is prior to the senses. .......
So, it is said that the self is self illuminating. No external light is required to sense it. Even the senses that go outward: eyes, ears, nose etc. are also not required.
There is one more step. We can examine the deep sleep state when even the mind is not operative. Yet we exist without sensing a world or "I".
But when we wake up we remember that we knew nothing. And that is knowing, implying consciousness.
So, at any given moment, "I am", the pure attttribute-less consciousness, underlies all our "I am xyz" experiences, spanning three states of waking, dreaming, and sleeping states.
