In her book, "The Crossroads of Should and Must," Elle Luna describes the snake as being the ancient sacred symbol for transformation. The snake must shed its skin in order to mature and grow. It's a painful process, but its very survival depends on this act. The snake's insides are literally outgrowing its outsides, and it must shed the outermost layer or risk becoming malnourished and possibly blind.
Perhaps you're in this process of shedding your skin. It's painful. It's hard. But we must trust the process, and the transformation that is magically taking place from the inside out.
