Just before Rikyu took his own life he said, “When I have this sword there is no Buddha and no Patriarchs.” He meant that when we have the sword of big mind, there is no dualistic world. The only thing which exists is this spirit. This kind of imperturbable spirit was always present in Rikyu’s tea ceremony. He never did anything in just a dualistic way; he was ready to die in each moment. In ceremony after ceremony he died, and he renewed himself. This is the spirit of the tea ceremony. This is how we bow.
