I'm not sure what view to take on Spiral Dynamics. It seems to me that your position on the stage isn't necessarily related to the "degree to which you are enlightened" [I'm using quotation marks because I think words and concepts fail in capturing the nature of enlightenment]. Because of this, idk how to view it.
I say this because it seems completely feasible to me that someone who embodies stage Red could be extremely conscious and enlightened. You could get a non neurotypical person who murders as a hobby but is at the same time, emotionally and psychologically healthy. The same goes for any many other stages.
And a second point I want to mention is that someone in stage (x+1) will not necessarily be more conscious that someone in stage (x). Sure, there might be a correlation between your stage and consciousness level.
But the fact that being in a higher stage doesn't gaurentee that you are of higher consciousness is indicitave of the fact that the foundational criteria used to put someone in a stage is separate from degree of consciousness, or the criteria is based upon on how different degrees of consciousness typically manifest (in contrast to telling you how different degrees of consciousness atypically manifests).
