TERMBASES
The term has two meanings. First, it refers to the state of one whole mass that existed before the universe took shape, often said to exist before qi (vital force) emerged. The multitude of organisms on earth all emanated from this state. Second, it refers to Chaos, king of the Central Region in a fable in Zhuangzi. According to the fable, Chaos had no eyes, nose, mouth or ears. Shu, king of the South Sea, and Hu, king of the North Sea, drilled seven apertures into Chaos and killed him. Zhuangzi (369?-286 BC)used this story to show the state of chaos of the world in which there is neither knowledge or wisdom, nor distinction between good and evil.
The term has three meanings. First, it indicates the original essence of all things. It is another name for dao (way). It is also referred to as taiyi (the supreme one). Second, it refers to the state of chaos before the separation of heaven and earth. The one was divided and transformed into heaven and earth. All things in heaven and on earth were produced from this Chaotic entity. Third, it indicates the unity of things, as opposed to “many” or “two.” The idea is to emphasize the unity among things which are different or opposite.
Qi (vital force) has a material existence independent of subjective consciousness and is the basic element of all physical beings. It is also the basis for the birth and existence of life and spirit. In addition, some thinkers have given a moral attribute to qi. Qi is in constant motion and change, and has no specific shape. Its concentration gives birth to a thing and its evaporation signals the end of that thing. Qi permeates all physical beings and their surroundings. Qi, as a philosophical concept, is different from what is commonly understood by the word qi (气), namely, air. Although things in liquid or solid form are different from things in air form, from the perspective of the ancient Chinese philosophy, their formation and existence are the results of the concentration of qi.
The term means the primal source from which all things originate, both animate and inanimate, including human beings. Yuan (元) manifests itself in different forms. In the Han Dynasty, it was considered a kind of primal physical material that both produced and made up the myriad things of the world. The Book of Changes divides yuan into two primal sources: the heavenly source which gives birth to the sun, moon, and stars, and the earthly source which creates all other things on earth. In The Spring and Autumn Annals, the term refers to the first year in its chronologies, symbolizing the start of a new historical period, and serving as the manifestation in the human world of the natural process in which things begin, end, and are replaced.
Taiji (the supreme ultimate) has three different meanings. First, it refers to the origin of the world. The ancient Chinese saw it either as qi (vital force) or yuanqi (primordial vital force) that permeates the chaotic world, or as a universal principle, i.e. Dao or li (理), or as wu (无). Second, it is used as a term of divination, referring to the initial state before divinatory numbers, the odd number one (written as —) and the even number two (written as – –), are applied or before the yarrow stems are divided. Divination is conducted on the basis of taiji. Third, it stands for the highest point or boundary of space.
