Ancient Taoist scholars believed that everything in the Universe can be classified into 5 basic Elements or Phases, these Elements being: Water, Wood, Fire, Earth and Metal.
These Elements are not static in nature, but representations of the transformation that occurs in the world around us; they are metaphors and symbols for describing how things interact and relate with each other. The 5 Elements follow the energy of the seasons. This theory is the basis for Chinese Medicine, Feng Shui, and the Elemental Woman ™ Leadership Program.
