A tea ceremony is a ritualized form of making tea practiced in Asian culture by the Chinese, Japanese,Indian, Taiwanese, and Vietnamese. The tea ceremony, literally translated as "way of tea" in Japanese, and "art of tea" in Chinese, is a cultural activity involving the ceremonial preparation and presentation of tea. The Japanese tea ceremony is better known, and was influenced by the Chinese tea culture during ancient and medieval times, starting in the 9th century when tea was first introduced to Japan from China. The Vietnamese tea ceremony, also influenced by its Chinese counterpart, is only performed during weddings and other religious rituals. One can also refer to the whole set of rituals, tools, gestures, etc. used in such ceremonies as tea culture. All of these tea ceremonies and rituals contain "an adoration of the beautiful among the sordid facts of everyday life", as well as refinement, an inner spiritual content, humility, restraint and simplicity "as all arts that partake the extraordinary, an artistic artificiality, abstractness, symbolism and formalism" to one degree or another.
At a very basic level, tea ceremonies are a formalized way of making tea, in a process which has been refined to yield the best taste. Historical documents on the subject include the 8th-century monograph "The Classic of Tea" and the 12th-century book Treatise on Tea.
When the tea ceremony is understood and practised to foster harmony in humanity, promote harmony with nature, discipline the mind, quiet the heart, and attain the purity of enlightenment, the art of tea becomes "teaism". The term "chadao" has two words, the first being 'tea' and the second the Chinese loanword tao/dao/ native suffix -ism (also Japanese: 主義), and could thus be read as 'teaism'. Another, more literal reading of the word is the 'way of tea' (茶 tea and 道 way), comparable with for example 弓道; the way of the bow. The term can be used to describe tea ceremony as the interests in tea culture and studies and pursued over time with self-cultivation. Teaism is mostly a simplistic mode of aesthetics, but there are subtle insights into ethics, and even metaphysics. Teaism is related to teamind. A sense of focus and concentration while under the influence of great tasting tea. Teaist is a person who performs or enjoys the art of tea and teaism. In Chinese and Japanese, as well as Korean traditional culture, there are well-developed teaisms.
