OPPOSITION
With the wheel come oppositions. There are 32 Hexagram oppositions in the wheel. Each opposed Hexagram is the true opposite of the other; as in the six yin lines of the second Gate opposite the six yang lines of the first Gate. There are also three oppositions that form definitions; 20/34, 40/37 and 43/23. The Sun and Earth and the Nodes of the Moon are exact oppositions. Also described as Polarity.
