Understanding Yin & Yang & 8 Trigrams

The Eight Trigrams Fundamentals

Wu Ji (无极) is described as Emptiness, Formless, Limitless, the Primordial and also the creation of perception. This is Wu Ji giving rise to Tai Ji (无极生太极).

From perception comes the recognition and differentiation of Yin and Yang, giving rise to Liang Yi. Next, Liang Yi gives rise to Yang Yi (represented by one full line (⚊)) and Yin Yi (represented by a broken line (⚋) ). 

From the interaction and union of Yin Yang comes Si Xiang, giving rise to the four seasons, the four cardinal directions and the four phenomena of Greater Yang (⚌), Lesser Yin (⚍), Lesser Yang (⚎) and Greater Yin (⚏).

Continuing the interaction and union of Yin Yang comes the Eight Trigrams, giving rise to the eight directions and vast myriad phenomena of Nature. Greater Yang gives rise to Qian Trigram (乾卦 ☰) and Dui Trigram (兑卦 ☱). Lesser Yin gives rise to Li Trigram (离卦 ☲) and Zhen Trigram (震卦 ☳). Lesser Yang gives rise to Xun Trigram (巽卦 ☴) and Kan Trigram (坎卦 ☵). Greater Yin gives rise to Gen Trigram (艮卦 ☶) and Kun Trigram (坤卦 ☷). This is Si Xiang giving rise to Eight Trigrams  (四象生八卦)).

9 Palaces

The final 8 symbols are derived from YIN and YANG and become the 8 Trigrams.

The 8 Trigrams symbols are placed inside the 9 boxes. Technically, the 9 boxes are called the 9 palaces. The center box is always empty. Each Box represents the BIG ENVIRONMENT.
