An "oil spot" temmoku ("Eye of Heaven") bowl on a dai (cup stand) similar to those used by monks in China and Japan to drink tea
Eisai was a firm believer in the health benefits of tea. Eisai also promoted a strict code of discipline for Japanese monastery life. The manner in which tea was prepared and shared among monks and temple patrons at memorial ceremonies and other important temple events was strictly regulated. Like most other parts of monastic life, tea ritual was based on the Chinese temple model.
