If we practice hard, concentrate on zazen, and organize our life so that we can sit well, we will find out what we are doing. But you have to be careful in the rules and way you establish. If it is too strict you will fail, if it is too loose, the rules will not work. Our way should be strict enough to have authority, an authority everyone should obey. Thu rules should be possible to observe.
This is how Zen tradition was built up, decided little by little, created by us in our practice. We cannot force anything. But once the rules have been decided, we should obey them completely until they are changed. It is not a matter of good or bad, convenient or inconvenient. You just do it without question. That way your mind is free.
