What is Tai Chi ?
“Tai” means the supreme, or the ultimate, which refers to the largest in the collection, that wherein everything else is included; “Chi” means one of the relativities. Taken together, “Tai Chi ”is an all-embracing concept, containing all relativity.
It is just like a circle, which contains countless angles without any angle being manifest; or like a piece of paper entirely covered in drawings appears dark, so that no drawing is visible. Another example is a sound wave, if all the frequencies are included, they cancel each other out and there is no sound (this is also the principle of noise-proof headphones).
The so-called Tai Chi is to clarify the process of universe from Wuji to Tai Chi, and then everything is created, among which Tai Chi is the state of Yin-Yang chaos before heaven and earth separated. According to the explanation of the I ching, the chaos "Wuji" becomes "Tai Chi", and further produce two platforms of Yin and Yang.
