Even after thirty years I still needed help. One common problem with meditation is that frequently people come to Zen practice having read books on Zen. They have been impressed with a story like the one where a newly arrived monk goes for his first interview with the teacher. We come to our practice with many ideas, most of them having to do with enlightenment, especially thinking that enlightenment is going to solve all our problems. Maybe even I'll walk six feet off the floor.
Meditation is very ordinary, very common.
In my tradition we say that the best monks are always the most ordinary. And my experience is that that is true. It will bring with it its own suffering, but nothing you will not be able to bear. If it brings crucifixion, it also brings resurrection. It doesn't matter about your age or what life you are leading.
