"What I do not believe is that Pluto is the soul and its relationship to the lunar nodes and its polarity point tells us the story of the soul. "
I imagine you're referring to Jeffrey Wolfe Green's work Elianah? I actually had Jeffrey do my chart several years ago and was not impressed with his interpretive skills. I did like his work with Pluto and the nodes but do not feel it gives the full multi-dimensional picture of the soul either. I think the work does point to incarnational issues chosen for further soul development however.
In terms of ascending, I am reminded of the saying "Those who would be first will be last". Those who have done the work to allow a higher vibrational fequency will be able to realize the benefits. Those who weigh themselves down with dualistic thinking and closed hearts will suffer the effects of dis-ease.
The other saying that comes to mind though is "A part cannot be where the whole is not". I read this as meaning we are one being collectively. If some ascend - all must ascend though the lift is relative. In quantum physics this is the butterfly effect in action.
Simple ain't easy.
