The tea ceremony is a well-orchestrated series of events. It takes place in a chashitsu, which is a building or a room in which the ceremony is performed. The ritual involves meeting the guests, a purification with fresh water in a stone basin, walking through the grounds of the teahouse, watching the tea being prepared, consuming food and drinking the tea.Together, the chashitsu, roji (tea garden), and mizaya (preparation rooom) should provide the best physical and spiritual setting for expressing this hospitality. There is also a religious dimension associated with Zen Buddhism ideais.The whole universe is experienced in the drinking of a bowl of tea by giving oneself over totally to the here and now and fully participating with a heart free from selfish desires. The ceremony is like a play consisting of two acts and an intermission.In the shoza, or first act, the guests enter the chashitsu and are served a light meal. Afterthis,the guests retire to the garden for a short break, '' the intermission'', and wait for the host to call them back. The second act is called the goza. First the host prepares matcha (thick tea) for the guests. He then prepares a second time and makes usucha (thin tea). When all of this is finished, the host and guests silently and respectfully bow to each other one last time, and the guests take their leave.
