「The long isolation of Japan from the rest of the world, so conductive to introspection, has been highly favourable to the development of Teaism. Our home and habits, costume and cuisine, porcelain, lacquer, painting-our very literature-all have been subject to its influence. No student of Japanese culture could ever ignore its presence. It has permeated the elegance of noble boudoirs, and entered the abode of the humble. Our peasants have learned to arrange flowers, our meanest labourer to offer his saturation to the rocks and waters. In our common parlance we speak of the man "with no tea" in him, when he is insusceptible to the serio-comic interests of the personal drama. Again we stigmatise the untamed aesthete who, regardless of the mundance tragedys, runs riot in the springtide of emancipated emotions, as one "with too much tea" in him.」
"The Book of Tea"(chales E.Tuttle Co.,Rutland,Vermont-Tokyo,Japan) From chapter;The Cup of Humanity pp.4-5
