Druidic name for the invisible force that governed both life and the material universe: Nwywre, symbolized by the serpent, which is a universal symbol already familiar to us from the statues of the Pharaohs, who were believed to represent the divinity on earth. According to Moreau, Nwywre 'was the creative power of the physical world'. Nothing happened without it. It was the cosmic fluid, the ether, the light and the great creative and divine Principle that linked Heaven and Earth. Its union with the other elements created life, movement and spirit. A Gallic bard sang that it is smaller than the smallest and bigger than worlds because it is subtleness and power itself. For the Druids, Nwywre was the thread mysterious linking the human world to the divine world
