When a heart is really alive,

then it is able to think live things. There is one heart all whose thoughts are strong, happy creatures, and whose very dreams are lives. When some pray, they lift heavy thoughts from the ground, only to drop them on it again; others send up their prayers in living shapes, this or that, the nearest likeness to each. All live things were thoughts to begin with, and are fit therefore to be used by those that think. When one says to the great Thinker: –“Here is one of thy thoughts: I am thinking it now!” that is a prayer – a word to the big heart from one of its own little hearts.
