My thoughts are that this sort of concept is one that could/would be interpreted differently by whomever reads it.
It opens more questions than provided answers, especially when you put the idea into practice in the modern world.
I'm sort of an individualist on this and think that perfection starts from within, but two perfect beings (man and woman) together could represent the best humanity has to offer... but i don't think either of them has to rely on the other for said perfection.
Thats just my jaded p.o.v tho. I've grown more singly than i ever did "paired" but from those flawed pairings, it did give me the proper perspectives on what i needed to do as an individual to be the best i could be "singly"
Obviously, couples would have a different interpretation of this, i would imagine.
Thought provoking, nonetheless.
