I participated in a tea ceremony in Kyoto yesterday. The tea master was an old wise man who told me that he travelled to the US recently and realized that the problem with the US is the sofa. It prevents people in the US from learning to sit properly, breathe properly and fundamentally takes the culture away from its center. He thought that people should remove their sofas and couches from their homes and hotels. I didn't argue with him. It's an interesting perspective. He was clearly wiser than me.
As we finish our remodel, I am reconsidering the purchase of a sofa. So if you come to visit you may have to sit on the floor.
