Well, no

. Why "One" me? I am a different person on this forum than with different friends, relations, lovers, colleagues, pets, my skin lice and digestive flora, in my head, in my dreams, drunk, on an operating table, driving a car, filing tax returns... I am a temporarily enduring collection of bio-physical-conscious-unconscious-socio-political processes, and like you say a forest eco-system, crowd, cosmos is similar. In fact I am an eco-system, a crowd, a cosmos...
I'm sure you've heard the concept that your physical body reproduces itself every 7 years yet you fundamentally remain the same person. This turns into the Soul debate - I cannot speak for you - but I Know that I am an essence beyond my body, mind, emotions and memories and I have always remained the same - although simultaneously I am all these things. Every spiritual discpline speaks of this (hence 'spiritual'). The fact that there are different ASPECTS of you explains the 330,000,000 million gods thing - they are all aspects of the One.
Oh yes - you all these things and more! haha
But where does the "One singular consciousness" come from? And what is the highest level - why posit a transcendent level "above" the cosmos? One thing I love about Deleuze & Guattari is their inversion of this cosmic-Zen intuition in their "plane of immanence" concept, which retains cosmic elements, but in a materialism of multiplicity, which jettisons the spiritual/transcendence/God/ego. And I don't accept this just because they say it cleverly; their exposition of it chimes with my own intuition.
Modern quantum physics has proven beyond a doubt the maleability of time and physical matter - in fact they have a model of 11 dimensions and suggest there are more. When i say 'above' i am not saying this in the sense of a heirarchy, only in the sense that at the 'highest' dimension there perhaps exists the energetic Source of this Universe. That is the 'Supreme' or the 'Point of Light' - 'Ishwara' as opposed to 'Brahman' in the Hindu scriptures, or the 'Wu Chi' as opposes to the 'Tao' in the Taoist scriptures.
Remember these are realms of reality beyond the thinking mind, and thus cannot really be comprehended by the mind, only directly experienced. But that doesn't really fit with the scathing intellectual critique of the western schizoid mind, does it? I can't comment on the Plane of Immanence because i don't know it yet. But i'll get back to you soon...

Pure consciousness. haha
That sounds like stereotyping, which I had not thought was the domain of the enlightened.
Not stereotyping, i'm not judging anyone, merely using what i've heard as an example.Interesting projection and assumption you have made, as i had never posited that i was enlightened. To me this again represents the 'atheist' assumption that once one understands God on an intellectual level then the journey is over and they are enlightened. My understanding differs slightly from most of the worlds population because it is based around knowledge and not blind faith - yet, the fear from the destructive skeptical individuals usually includes the notion that once they have it figured out then they will have to do something about it, which includes life changes etc as i explained before. After all - you don't want to be one of those nerdy Christian idiots, do you? There you have it - your egoic illusion-of-self struggles to align itself with things that you Know to be True...
In case you hadn't consciously realised - you probably have a massively emotional resistance to the idea that there 'is a God' because of the systematic raping of spirituality and truth by the Christian church over the last 2000 years. It took me a long time to clear away all the emotional resistance i had to the idea of 'God' because I simply didn't want to associate myself to the 'style' of the idea of 'God'. The word God is dead, as the Reality of What Is is so far removed from the stigma of the word 'God' that one can posit that the consciousness of the everyday human is completely schizophrenic - split, contradictory - like a computer stuffed with conflicting data causing it to crash.
Even now, after months-years of knowing that the words 'God' and 'Universe' mean the same thing, and that the concept of 'staying close to Great Spirit' or 'sticking to the truth' is the same as 'being One with God', every time i hear or think of the word, it still rings in my ear as Christian clap-trap. Don't panic! Its the mind trying to align itself...
