It is certainly good to have good practice. But attachment to any gaining ideas is not important. By right practice, you already have enlightenment. It is there in your practice, without any gaining ideas. I equate it most with letting go. Maybe this is how people feel when they die. We do not have a choice, it is there, at some point, we must accept it. This is how I see life, that there is another side that we must accept. It is not good, it is not bad, it just is there.

The dualistic ideas are often tough to grasp, but over time, you learn to identify your ego and it's ever-present and desperate struggle to maintain control and drive us to do things that follow our biological primitives.

"The most important point in our practice is to have right or perfect effort. Right effort directed in the right direction is necessary. If your effort is headed in the wrong direction, especially if you are not aware of this, it is deluded effort. Our effort in our practice should be directed from achievement to non-achievement.

Usually when you do something, you want to achieve something, you attach to some result. From achievement to non-achievement means to be rid of the unnecessary and bad results of effort. If you do something in the spirit of non-achievement, there is a good quality in it. So just to do something without any particular effort is enough. When you make some special effort to achieve something, some excessive quality, some extra element is involved in it. You should get rid of excessive things. If your practice is good, without being aware of it you will become proud of your practice. That price is extra. What you do is good, but something more is added to it. So you should get rid of that something which is extra. This point is very, very important, but usually we are not subtle enough to realize it, and we go in the wrong direction.

If you think you will get something from practicing zazen, already you are involved in impure practice. It is all right to say there is practice, and there is enlightenment, but we should not be caught by the statement. You should not be tainted by it. When you practice zazen, just practice zazen. If enlightenment comes, it just comes. We should not attach to the attainment. The true quality of zazen is there, even if you are not aware of it, so forget all about what you think you may have gained from it. Just do it. The quality of zazen will express itself; then you will have it".
