The Book of Tea (1906) by Okakura Kakuzō is a long essay which examines the role of chadō (Teaism) in the aesthetic and cultural aspects of Japanese life. The author explains Teaism as “a philosophy founded on the adoration of the beautiful among the sordid facts of everyday existence”. Originally written in English for a western audience, the essay deals with the spiritual traditions of Zen and Taoism, as well as the secular side of tea in Japanese life. The author shows how tea as a metaphor inspired the elegant simplicity which characterizes - inter alia - the art and architecture of Japan. According to the philosopher Tomonobu Imamichi, Martin Heidegger's concept of “Dasein” was inspired by Kakuzō’s expression “being-in-the-worldness” for the philosophy of Zhuangzi who composed a foundational text of the Tao. Kakuzó concludes that Teaism in itself serves as a universal remedy for promoting peace and tranquillity.
