Art enables us to find ourselves and lose ourselves at the same time. The mind that responds to the intellectual and spiritual values that lie hidden in a poem, a painting, or a piece of music, discovers a spiritual vitality that lifts it above itself, takes it out of itself, and makes it present to itself on a level of being that it did not know it could ever achieve.
It takes practice to spot angelic presences. But practice alone is not enough, unless one can practice being taken by surprise.
