Zen is the same as meditation and you cannot do meditation. You have to be in meditation. Now you are paying attention to me, and I say, “You pay attention to yourself,” how can you do it?
When you are in meditation your attention is inside. But how can you do it? Only when the Kundalini rises. Her movement upward, catches your attention inside. So you know about your centers as a self-knowledge and you know about others’ centers.
