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.
Art is both love and friendship, and understanding; the desire to give. It is not charity, which is the giving of things, it is more than kindness, which is the giving of self. It is both the taking and giving of beauty, the turning out to the light of the inner folds of awareness of the spirit.
~ Ansel Adams in a letter to Cedric Wright, 1937, as quoted in ART AS A WAY OF LIFE, ed. by Roderick MacIver
I know of no sculpture, painting or music that exceeds the compelling spiritual command of the soaring shape of granite cliff and dome, of patina of light on rock and forest, and of the thunder and whispering of the falling, flowing waters.
