That chart you've constructed seems like a simplified version of the noble eight-fold path, nice work, working it through!
Basic Buddhism says compassion for others (as the root of morality) is one of the paths to higher consciousness, and I couldn't agree more.
However, as to the unified state... personally I'm almost certainly too in my head to ever get there... I'm absolutely that bloke in the temple having perpetual tea poured into his cup...
Giving up intellectualism is absolutely the biggest barrier to my unification-evolution, or perhaps I shouldn't see it as a barrier, or is that thought just my attachment to... thought?!?
"Giving up intellectualism" is not required. I don't adhere to that definition of higher consciousness. Look at the word consciousness. To be with knowledge. The more conscious awareness we have of meaningful quality truth about our world and ourselves in reality, the more we increase conscious awareness and that elevates our understanding, and evolves consciousness to higher consciousness states of awareness in reality. Emotional states or beliefs. aren't what I talk about in higher consciousness.
There is nothing wrong with thought. Thought is great. I don't adhere to any religious ideologies. Nothingness is not the way forward. Being without thought is not the way forward to resolve problems in humanity. Isolation and self-refection on the "self" or "being" alone is not the way forward.
I agree entirely, maybe I wasn't clear enough... personally I think I'm too imbalanced towards JUST thinking... I fully accept it's all part of 'evolving'.
I also don't adhere to any religious ideology...I only mentioned the Noble Eightfold Path because, honestly, your conceptualization of evolving above fits in very well Bikkhu Bodhi's conceptualization of the 'structure' of human consciousness and the evolution through higher states... up to the 'base of infinite space' and all that... - link to PDF - http://www.buddhanet.net/pdf_file/noble8path6.pdf
It's quite an 'intellectual' account of Buddhist philosophy.
NB also this is very much 'non-ideological Buddhism - the kind that says 'listen/ read in a spirit of skepticism, and if you don't like something, reject it and if you don't like anything, go your own way (in peace, of course'!)
Anyway, TBH these days I'm leaning much more towards finding my own peace of mind in just trying to be nice to people and through living a non-harming lifestyle...
