It is important to have a secret, a premonition of things unknown. It fills life with something impersonal, a numinosum. One who has never experienced that has missed something important. We must sense that we live in a world which in some respects is mysterious; that things happen and can be experienced which remain inexplicable; that not everything which happens can be anticipated. The unexpected and the incredible belong in this world. Only then is life whole. For me the world has from the beginning been infinite and ungraspable.
The principles of tea Rikyu (the most revered Japanese master, 16th century) set forth are harmony, respect, purity and tranquility. Harmony is the oneness of host and guest with the flowing rhythms of nature ... Respect is the sincerity of heart that allows one to have an open relationship with the other participants, humbly recognizing their dignity ... Purity is removing the dust of the world from one's heart and mind ... Tranquility comes with the constant practice of harmony, respect, and purity in everyday life. In this state of mind, having found peace and beauty within oneself, a bowl of tea can truly be shared with another.
