answer:It varies, with most of the variants being classical Zen stuff. In my training, I went through a typical progression: Years of focusing on the breath, many more years focusing on koans, then many more years just sitting. Nowadays I teach, so at any given time I have students who are at various points in that progression. To better help them, I often revisit whatever practice they’re doing. That refreshes my memory of what that particular practice is like, so I can better relate to their problems and give them better guidance. That’s especially true of koans. I work on them right along with the student, even if I’ve been over that particular koan a million times already. But sometimes I’ll even spend time with a “beginner’s” practice, like counting breaths, just as a refresher. Your “no idea where this is leading” and “not worried about it at all” is a wonderful way to work. It can take so long to find that unexpectant openness. Virtually everybody takes up a practice imagining where it will take them and get discouraged when they can’t plot some kind of progress toward that goal. But it isn’t about getting somewhere else; it’s about thoroughly being right where you are.
