TaegeukTaegeuk (, thɛgɯk̚) is a Korean term meaning "supreme ultimate", although it can also be translated as "great polarity / duality". The term and its overall concept is related to the Chinese Taiji (Wade-Giles: T'ai-chi). The symbol was chosen for the design of the Korean national flag in the 1880s. It swaps out the black and white color scheme often seen in most taijitu illustrations and substituting blue and red, respectively, along with a horizontal separator, as opposed to vertical.
GankyilThe Gankyil (, Lhasa /kã˥ kjhiː˥/) or "wheel of joy" (ānanda-cakra) is a symbol and ritual tool used in Tibetan and East Asian Buddhism. It is composed of three (sometimes two or four) swirling and interconnected blades. The traditional spinning direction is clockwise (right turning), but the counter-clockwise ones are also common. The gankyil as inner wheel of the dharmachakra is depicted on the Flag of Sikkim, Joseon, and is also depicted on the Flag of Tibet and Emblem of Tibet.
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).
