Early on in my challenge year I took a Japanese Tea Ceremony lesson for challenge no. 17. The experience was great, and while I don't really have the funds for continuous lessons (the Japanese study the way of tea for lifetimes), that initial introduction provided me with a basic understanding of what this whole thing is all about. Yes, there are a million and one details to conquer within this art, but I am confident I can learn enough to perform my own bare-bones ceremony for a few of my friends.
As a step toward performing my own ceremony, I found a book that outlines all of the steps, the equipment needed for each step, and many other components (etiquette, the aesthetics of the room, the history):
The next step, after reading the book of course, is to purchase all of the tea tools. Stay tuned for my tea ceremony haul.
