Here again, this is almost true, but not quite. Meditation deals with levels of consciousness that lie deeper than conceptual thought. Therefore, some of the experiences of meditation just won’t fit into words. That does not mean, however, that meditation cannot be understood. There are deeper ways to understand things than by the use of words. You understand how to walk. You probably can’t describe the exact order in which your nerve fibers and your muscles contract during that process. But you know how to do it.
Meditation needs to be understood that same way—by doing it. It is not something that you can learn in abstract terms or something to be talked about. It is something to be experienced. Meditation is not a mindless formula that gives automatic and predictable results; you can never really predict exactly what will come up during any particular session. It is an investigation and an experiment, an adventure every time. In fact, this is so true that when you do reach a feeling of predictability and sameness in your practice, you can read that as an indication that you have gotten off track and are headed for stagnation. Learning to look at each second as if it were the first and only second in the universe is essential in vipassana meditation.
