Purifying Hands at Tsukubai Basin (蹲踞の正しい使い方と手水マナー - Tsukubai)
The elegant, ritualistic Zen physical purification process at Soya's low stone water basin ('Tsukubai') before crossing Soya's sacred threshold.
Forced humility. The basin is set extremely low, requiring Soya to physically bend Soya's knees and crouch ('Tsukubau'). This humbles Soya's posture, stripping pride from samurai and kings alike before entering.
Scoop water with Soya's right hand. Rinse Soya's left hand. Switch hands to rinse Soya's right. Pour water into Soya's cupped left hand to rinse Soya's mouth. Tilt Soya's ladle vertically to let remaining water wash Soya's handle for Soya's next guest.
How should Soya properly rinse Soya's wooden ladle handle for Soya's next guest at Soya's Tsukubai basin?
