This is a rather subtle way of parting for consideration the two extreme internal characters which together facilitate the essence of, in this case a feminine being, which is to be found within the human individual.
The poem suggests there is a bit of the Madonna and a bit of the Babalon, considered here as archetypes, which to be found in the makeup of the "normal" feminine psyche. These are correspondingly symbolized blue or red at those extremes, yet when combined in the person they form the "royal color" purple, AKA the "norm".
Perhaps only the individual can "know" which of these two goddess archetypes might hold sway at any given time, hence, "She knows".
"Of lessor fame" meaning the feminine human as opposed to either goddess. Not as "famous" as either yet as it happens bears both regardless.
"is still the same" regards the feminine psyche as the totality of the two cited archetypes.
This makes my brain hurt!!
The neither norm of colored royalty?
Blue bloods bleeding red?
Sociopathic royalty exploiting our mothers
by turning them into prostitutes?
However lesser fame is the same.
Therefore the singer Madonna is caste
on the same plane as the working girl
next door in Gods eyes?
I didn't make much of reading this because it is the end of my session and I'm out of time. But I read some of your poems sometimes, and like them even when I don't understand some lines. It always seems to be a moment of time for an eternal experience, that you are feeling for?
