It can be understood, both by reasoning and insight, that the eternal essence of things has a dualistic character. It has been a matter of discussion since ancient times across human cultures, philosophies, and religions.
The most prominent duality consists of two eternal polar opposites, whose origin is unexplainable with our current knowledge and will probably remain so regardless of technological or scientific advancement.
One side of this eternal duality has to do with the order that is observed across the whole universe, space and time, our mathematical equations, the logic in our minds, etc. Let’s baptize it, though naming it makes it lose its appeal or adds irrelevant context. Let it be called LOGOS, as it has been named many times before across philosophy and religion. Logos is the essential spark of logic and of everything that follows rules. It is the necessity of this world.
The Logos keeps everything coherent and in order. It is the reason we see deterministic behaviors in the world and predict outcomes.
Something that is orthogonal to this eternal essence is the feeling we get from existing: the qualia, consciousness, experience, the screen inside us, the underlying substance that makes us feel alive, and the one without which everything would be “dark” and meaningless. Let’s temporarily baptize it LIGHT, using the metaphor already present in the phrase “light of consciousness.” It is the one that gives quality to things; it colors our existence.
The next question is how these two are glued together. Are they two aspects of the same Oneness? Or is there a third glue or connector? And even if there is a third, or possibly more connectors, perhaps infinitely many, are they still forms of the One?
