Is Zen meditation difficult?
Yes, Zen is very difficult. Not because of the posture, or sitting motionless for a long time – this you can learn. It is very difficult, because the aim of Zen is just to do whatever you are doing right now, nothing more, and nothing less. So, if your are sitting, you are just sitting. When you are walking, or washing the dishes, you are just doing that. Nothing else. This is very difficult. To solely concentrate on a single action. Try it, and see for yourself.
