Paradox, the resolution of opposites at a higher level of understanding is a very confusing idea and that is because the confusion can only be resolved at a higher level of understanding.
Let us think about light and dark and the unconscious associations connected with them as an example. In the first place you can't have one without the other so right away you know they don't exist they are simply the product of dualistic thinking. No other animal thinks like that. No other animal experiences existential angst. This means that light and dark are of equal value, one not being better than the other, since neither one exists.
So what does exist. I think it is our truth as determined by our feelings. Some feelings we call light and some we call dark, but sadly we do not feel them so they never exist as they really are. Instead we experience opinions about how we feel and react to how we feel about those opinions. And we invest in those opinions by believing the are real in the sense of accurately reflection reality. But we don't see reality. We see only duality
The phenomenon of duality can collapse but never by the effort of ego because the belief in duality creates the ego and the ego is there to protect us from the horrible truth that everything we believe is a lie. But it happens sometimes for those who suffer immeasurably and let go, or to those who perhaps practice forms of meditation designed to kill thought. Or perthaps we have some peak experience and the glorious beauty of the universe gets past our filters.
Additionally, since there is no light and dark there are on other opposites either, no such thing as good and evil. All there is are opinions we have that we internalized and suppressed out of conscious awareness that we are bad people when we feel certain feelings. As the result of a rather unusual and fortuitous set of experiences earlier in my life, where the darkness came crashing in to claim me, I was forced to stare hopelessness in the face to the point where I was forced to realize there was no way out for me. It was going to be impossible for me every again to be happy and I surrendered to that reality. That is when duality collapsed for me and I experienced calmness and peace. I understood everything is meaningless including my need for meaning. There was no such need. It was a fiction created by duality.
So you will excuse me if i suggest you do not see the darkness in me but that when you look at me you may begin to see what you don't want to see, what I couldn't avoid seeing myself. I went into uncharted waters where the monsters lurk and now they are my friends. At depth and burned to ash, we are the sun, the moon, and the star born to hoot and cavort as we swing through life's trees.
