This therefore is Mathematics:
She reminds you of the invisible forms of the soul;
She gives life to her own discoveries;
She awakens the mind and purifies the intellect;
She brings light to our intrinsic ideas;
She abolishes oblivion and ignorance which are ours by birth.

— Proclus

God did not create man in his image; man created God in his image.

The end of distances is the end of seeking them

You should do your utmost to become like your idols, and when you do become like them, throw them away and find better ones.

Now we have the right to give this being the well-known name that always designates what no power of imagination, no flight of the boldest fantasy, no intently devout heart, no abstract thinking however profound, no enraptured and transported spirit has ever attained: God. But this basic unity is of the past; it no longer is. It has, by changing its being, totally and completely shattered itself. God has died and his death was the life of the world."
- Philipp Mainländer

We do not fall in love with someone because we know them; we fall in love because we don't
