The Book of Tea
When tea is more than a drink and the tea ceremony is understood and practiced 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.  And it 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, Japanese, and Korean cultures, they all have well-developed teaism.
