Tea is nought but this: first you heat the water, then you make the tea. Then you drink it properly. That is all you need to know.

Sen no Rikyū (1522 CE-1591 CE), Sen no Rikyū, also known simply as Rikyū, was a Japanese tea master considered the most important influence on the chanoyu, the Japanese "Way of Tea", particularly the tradition of wabi-cha. He was also the first to emphasize several key aspects of the ceremony, including rustic simplicity, directness of approach and honesty of self. Originating from the Sengoku and Azuchi–Momoyama periods, these aspects of the tea ceremony persist.
