Entering through Uchimon, one is led to the Chisen-Kaiyushiki garden (Japanese style garden with a path around a central pond and spring).  Traditionally, the tea ceremony uses a classification scheme that includes “Shin”( formal), “Gyou” (flowing), “Sou” (free)to describe the quality of implements.  Following this classification, Uchimon refers to the kekkai (boundary) at which the world of the sacred “shin” returns to the mundane world of “Sou.”
