Great Effort, I think of as the hinge-point of our practice. If we don't have this great effort, then we really don't have a practice. Because unless we bring our practice to the difficult parts of our lives, it's not much of a practice. In fact, what often seems to happen is many people will practice when things get difficult in their life, but as soon as things start to get better, then they don't feel like they need it anymore.
So in a sense for a Zen practice, great effort really needs to be applied when things are going well because that's the time it's easy to fall asleep. When we're suffering it's easy to keep this great question, “What am I? What is this life about?” But when things are going well, we can get very complacent.
Zen Master Seung Sahn used to say, “A good situation is really a bad situation, and a bad situation is really a good situation.” This is in a sense what that means. If things are going well, you can easily lose your direction. You can easily fall into selfishness and self-centeredness. But when things are difficult, then you have to call into question all your different assumptions, your different beliefs, and ideas.
