Crystal Quotations

Every particular in nature, a leaf, a drop, a crystal, a moment of time is related to the whole, and partakes of the perfection of the whole.
Ralph Waldo Emerson

If you don't die of thirst, there are blessings in the desert. You can be pulled into limitlessness, which we all yearn for, or you can do the beauty of minutiae, the scrimshaw of tiny and precise. The sky is your ocean, and the crystal silence will uplift you like great gospel music, or Neil Young.
Anne Lamott

In a state of grace, the soul is like a well of limpid water, from which flow only streams of clearest crystal. Its works are pleasing both to God and man, rising from the River of Life, beside which it is rooted like a tree.
Saint Teresa of Avila

So that the record of history is absolutely crystal clear. That there is no alternative way, so far discovered, of improving the lot of the ordinary people that can hold a candle to the productive activities that are unleashed by a free enterprise system.
Milton Friedman
