The true potency of the full moon energies occurs when the moon is full in the sign opposite that of the Sun. When it is in “opposition” to the sun, (180 degrees) a perfect balance is formed in the zodiac. It is a big yin/yang symbol in the cosmos. It is the tension and intersection of the two sides of this polarity that are auspicious. This polarity hangs between illusion and reality, or nebulous emotion and structured materialness.
