"The intermingling of the elements forms the visible figure of the manifested universe, which is expressed through form and motion. This figure represents the composition of the elements in their mutual interpenetration and correspondence, according to number, proportion, and harmony, by which all things are brought forth and preserved. Through this ordering, the inner essence becomes visible, and the hidden powers of nature are revealed in their effects and operations. Thus the figure serves as a mirror of creation, showing how unity unfolds into multiplicity, and how multiplicity returns again into unity. Therefore it is rightly called the central form of the elements, in which their balance and order are contained."
