竹心喜共清風 Chikushin seifuu to tomo ni yorokobu
(The bamboo spirit [kokoro] rejoices with pure cool breeze.)
This is one of 禅語 Zengo (Zen statements) which often carry metaphorical meanings.
I think it depicts the ideal situation where a host and guests truly enjoy the moment of tea ceremony together. And this situation could be achieved when we keep the 4 principles of Tea in mind, 和敬清寂 Wa, Kei, Sei, Jyaku, as everyone respects each other, thus forming harmony.
It is a perfect statement to have in a tea room which is carefully set up by a host where each guest is treated equally and sincerely.
With the beautiful bamboo sumi-e, I could feel as if the cool breeze was coming through the scroll itself.
In this world of uncertainty, whatever we might face or wherever we would be headed for, by knowing that each of us is the essential component of the world, just as gentle wind blows and rustles each bamboo leaf, hopefully we could keep moving forward in the right direction.
