Contradictions are not a problem for Reality. It is replete with them. Contradictions are only a problem for the mind!
So it depends where you stand on the map vs. territory problem. If you believe that the map is reality, contradictions are a problem. If you believe in the territory, however, there is no problem. Up to you lol!
I guess not understanding is part of the territory also..?
And also not needing to understand especially if coherency is the measure of understanding.
