Possibly my favorite quote in the world:

To see a World in a Grain of Sand
And a Heaven in a Wild Flower,
Hold Infinity in the palm of your hand
And Eternity in an hour.

Those words “have become among William Blake’s most oft-quoted lines, and argue for seeing the grand in the very small, and pondering those metaphysical concepts beyond the comprehension of man by observing them at a local level.”
