PISCES (Feb. 19-March 20): "God changes caterpillars into butterflies, sand into pearls, and coal into diamonds by using time and pressure," says pastor Rick Warren. "He is working on you, too." Let's make that idea your meditation. If the word "God" doesn't suit you, substitute "life," "nature," or "Wakan Tanka," the Lakotan term for "The Great Mystery." The essential point is that you are being worked on and shaped by forces beyond your conscious awareness. Some of them are vast and impersonal, like your culture, the media, and the entertainment industry. Others are intimate and close at hand, like your genes, your childhood imprints, and the characters you encounter daily. Now is an excellent time to contemplate all the influences that make you who you are.
