Form your life humanly, and you have done enough: but you will never reach the height of art and the depth of science without something divine.

Nothing is more piquant than when a man of genius possesses mannerisms; not so when they possess him -- this leads to spiritual petrification.

What do the few existing mystics still do? -- They more or less mold the raw chaos of already existing religion. But only in an isolated, insignificant manner, through feeble attempts.
