in relation to the trinity:

"I remember that I possess memory and understanding and will; I understand that I understand and will and remember: I will my own willing and remembering and understanding. And I remember at the same time the whole of my memory and understanding and will." - Augustine

the unity of selfhood - three in one-ness

similarly love requires a lover, one who is loved, and the love that unites them, in a kind of three-in-oneness, for in speaking of these three, we are speaking of one thing, love. - Augustine

chew on that for a few centuries
