In reflecting on our problems, we should include ourselves.
There should not be any particular teaching. Teaching is in each moment.
Zen is everywhere.... But for you, Zen is right here.
Instead of criticizing, find out how to help.
So it is not a matter of whether it is possible to attain Buddhahood, or if it is possible to make a tile a jewel. But just to work, just to live in this world with this understanding is the most important point, and that is our practice. That is true zazen.
Zen is not some kind of excitement, but concentration on our usual everyday routine.
