Much of the material in this section on Seasons of the Year, came from The Robin Armstrong School of Astrology, RASA, Level 8, Class # 9, where there are several videos on youtube explaining this material.
The material here presents the foundational alignment of the I Ching to the seasons. It is not presented as a theory, but rather as a system for measuring the light and the dark. The logic that goes with this is revealed, and then the associations of the lines of the hexagrams to the degrees of the zodiac are shown. With the association to the zodiac, the colour correspondence to each hexagram becomes clear.
