Tsukubai Zenigata Granite Water Basin The Japanese Tsukubai Zenigata Granite Water Basin is a classic Japanese tea garden basin designed to represent an antique coin, Kosen. It features a square water pool in the middle, surrounded by four Japanese characters within a circle basin. This basin is found in the Ryoan-ji temple in Kyoto and has been translated in several different ways. The top character is Self, to the left is Knows, to the right is Only, and the bottom is Contentment. On the basin, the four symbols say, “Self knows only contentment,” or “ware, tada, taru (wo) shiru,” meaning, “I only sufficiency know.” The Buddhist teaching of humility and abundance translates, “you have all that you need.” The Ryoan-ji used the basin to provide ritual washing – a person must bow/bend over to use the basin. The word tsukubai means to crouch, which shows humility and a sign of reverence, meaning you are content and at peace which is a state of higher self. Available in 12″, 16″, 18″ and 24″ sizes. The beautiful salt and pepper granite will darken over time. Click HERE to learn more about setting up your basin.
