In order to evoke and emphasize an unbiased polarity in the lines of the hexagrams, I have altered the original text to the extent of identifying each line as either "dynamic" or "magnetic." This nomenclature is taken from the philosophy of Actualism, as developed by Russell Schofield and described by Ralph Metzner in his book Know Your Type -- Maps of Identity (1979):
Actualism distinguishes two basic polarities of energy relationships, dynamic and magnetic. The dynamic pole is outgoing, expressive, giving, masculine, yang...The magnetic pole is incoming, receptive, feminine, yin... In a broader sense, the dynamic aspect of consciousness is functional and the magnetic is structural. Function moves through structure, and is given body or form by its structure. Energy (dynamic) is embodied (in-formed) into matter (magnetic).
Some examples of this principle are: the flow of electric current (dynamic) through a conductor (magnetic); the flow of life through the human body; and the structuring of sound energy into meaningful verbal patterns. An unstructured dynamic expression is random and incoherent; a magnetic without dynamic function is an empty and powerless structure
