'Has anyone else perceived these concepts like this?'
It was a question Damien asked himself multiple times while he was with Existence. It was such a unique experience that he really couldn't imagine someone else doing the same.
But…he had the subtle understanding that this was his path to becoming Absolute, so hadn't at least one other person experienced the same thing?
He only had such thoughts because he didn't understand how much of an outlier he was.
Living beings simply weren't meant to perceive the emotions of these concepts. Before Damien came, these emotions were hidden and vague. He was the one who came along and gave them deeper meaning, bolstering the concepts in the process.
However, even the primal emotions felt by Nonexistence before his arrival weren't privy to anyone else.
