I ChingThe I Ching or Yi Jing (, AUDYiJing.oggyi4-jing1), usually translated Book of Changes or Classic of Changes, is an ancient Chinese divination text that is among the oldest of the Chinese classics. Originally a divination manual in the Western Zhou period (1000750), the I Ching was transformed over the course of the Warring States and early imperial periods (500200) into a cosmological text with a series of philosophical commentaries known as the "Ten Wings".
BaguaThe bagua (pinyin) or pa-kua (Wade-Giles) (八卦) are a set of eight symbols that originated in China, used in Daoist / 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. Due to their tripartite structure, they are often referred to as Eight Trigrams in English. The trigrams are related to Yijing and Taiji philosophy, and the Wuxing, or "five elements".
Taiji (philosophy)In Chinese philosophy, Taiji or Tai chi () is a cosmological term for the "Supreme Ultimate" state of the world and affairs - the interaction of matter and space, the relation of the body and mind. While Wuji is undifferentiated, timeless, absolute, infinite potential, Taiji is often portrayed as differentiated, dualistic, and relative. Yin and yang originate from Wuji to become Taiji. Compared with wuji (, meaning 'without limit'), Taiji describes movement and change wherein limits do arise.
TaijituIn Chinese philosophy, a taijitu () is a symbol or diagram () representing Taiji () in both its monist (wuji) and its dualist (yin and yang) aspects. Such a diagram was first introduced by Neo-Confucian philosopher Zhou Dunyi (周敦頤; 1017–1073) of the Song Dynasty in his Taijitu shuo (太極圖說). The modern Taoist canon, compiled during the Ming era, has at least half a dozen variants of such taijitu. The two most similar are the "Taiji Primal Heaven" () and the "wuji" () diagrams, both of which have been extensively studied during the Qing period for their possible connection with Zhou Dunyi's taijitu.
Yin and yangYin and yang (jɪn and jæŋ), yinyang, or yin-yang is a Chinese philosophical concept that describes opposite but interconnected forces. In Chinese cosmology, the universe creates itself out of a primary chaos of material energy, organized into the cycles of yin and yang and formed into objects and lives. Yin is the receptive and yang the active principle, seen in all forms of change and difference such as the annual cycle (winter and summer), the landscape (north-facing shade and south-facing brightness), sex (female and male), the formation of both men and women as characters, and sociopolitical history (disorder and order).
HuainanziThe Huainanzi is an ancient Chinese text that consists of a collection of essays that resulted from a series of scholarly debates held at the court of Liu An, Prince of Huainan, sometime before 139. The Huainanzi blends Daoist, Confucianist, and Legalist concepts, including theories such as yin and yang and Wu Xing theories. The Huainanzis essays are all connected to one primary goal: attempting to define the necessary conditions for perfect socio-political order.
TaoTao or Dao (道) is the natural order of the universe, whose character one's intuition must discern to realize the potential for individual wisdom, as conceived in the context of East Asian philosophy, East Asian religions, or any other philosophy or religion that aligns to this principle. This seeing of life cannot be grasped as a concept. Rather, it is seen through actual living experience of one's everyday being. Its name, Tao or Dao , came from Chinese, where it signifies the way, path, route, road, or sometimes more loosely doctrine, principle, or holistic belief.
