"Mu Ichimotsu Chū Mujinzō" (Without a single thing, there is an inexhaustible treasure) This phrase originates from a line in a poem by the Chinese poet Su Dongpo: "Mu Ichimotsu Mujinzō, Hana ari, Tsuki ari, Rōdai ari" (Without a single thing, there is an inexhaustible treasure; there are flowers, the moon, and pavilions). This saying means that if you eliminate attachments (a single thing), there are no limits to possibilities, and it is regarded as an important spirit in the tea ceremony as well.
