Wow! So beautiful!
To me, it is a message for entire humanity that a wooden ball can make a beautiful musical sound on the bridge made of thousands pieces of wood. This is an example of a love and harmony that today's world should have so that we can create a beautiful world to live together. This is called " the sound of one hand clap". I should say 1+1000= 1, it's a unity of whole. This is what we entire human should unite as a whole like the ocean, like the sky, like the sound that came from this musical ball rolling down on its own with the beautiful siund of love and harmony.
