The most revered of Japanese tea ceremonies is the "Seiuchi" or "Floating Lotus Blossom". It takes a month to complete and must be carried out in total darkness by somebody who is unknown in the household. After the tea has been correctly prepared it is drunk by the person who has performed the ceremony. The final act is for the room to be left exactly the way it was before the ceremony started and for the performer of the ceremony to leave the house unnoticed by the householders - in the same way that the person entered. Some people, however, claim to follow the ceremony but just leave a room locked and darkened for a month.
