BAGUA 八卦  are eight symbols used in Taoist cosmology to represent the fundamental principles of reality, seen as a range of eight interrelated concepts. Each consists of three lines, each line either “broken” or “unbroken”, respectively representing yin or yang, 0 or 1 forming binary numbers 000-111 (0 to 7). Due to their tripartite structure, they are often referred to as Eight Trigrams in English. The trigrams are related to Taiji or Taegeuk philosophy, Taijiquan and the Wuxing, or “five elements”. The relationships between the trigrams are represented in two arrangements, the Primordial (先天八卦), “Earlier Heaven” or “Fu Xi” bagua (伏羲八卦), and the Manifested (後天八卦), “Later Heaven,” or “King Wen” bagua. The trigrams have correspondences in astronomy, astrology, geography, geomancy, anatomy, the family, and elsewhere. The ancient Chinese classic, I Ching (Pinyin: Yi Jing), consists of the 64 pairwise permutations of trigrams, referred to as “hexagrams”, along with commentary on each one~08
