But does that mean that yaweh and lucider are the same being in a higher dimension?
Duality applies to two parts which together make a whole, or can be two sides of one whole. Existent and Non existent. Yin and Yang. Life and Death. Seen and Unseen, to name a few.
Note here as well, opposites do not automatically represent a Duality, only if the opposites represent a singular whole. Light and Dark can be seen as one such opposite that together creates a whole, while Ignorance and Gnosis are not as they are two wholly different states which do not together make up a single whole.
Satan and the imaginary nonsense thoughtform invented by the jews have absolutely no correlation in any way whatsoever. "Yahweh" doesn't even exist on any higher dimension, because it is merely a thoughtform created by jews.
To even suggest this sort of thing, there is a fundamental lack of understanding to what a Duality represents, and a total absence of understanding to what Satan and what Gods are.
When a being is beyond duality, it means it is the whole of both in perfect unification, but also a state that is outside of the whole of the two. A middle state is born that is neither one or the other, but is both at the same time (Which is a Duality in itself interestingly enough, you can begin to see how this loops on itself to create a new state). Satan is Seen and Unseen, Present and Non Present, to name a few. He is both simultaneously, on our dimension, and everywhere. It is an expression of both at once, and also beyond both.
Lastly, not all Duality is equal. Some are higher forms than others, permeating more of All than others. This relates to the forms they take, what forms they represent, and what the duality rules over and is ruled by. Some states of Duality are higher than others, and more unobtainable than others, some more observable than others.
At the root of it, something has to be of a Dual nature to be able to form a Duality.
Satan is infinitely removed from that lowly crap. There is never a Duality there. Infinite and Infinitesimal are a Duality. Garbage and The Absolute are not. Garbage is just garbage, while Satan is Satan.
