Helping Concentration, Fostering Discernment
ฐานิสสโร ภิกขุ

Once the mind is settled down, give it time to stay there. Don’t be in too great a hurry to move on. Here the questions are, “Which parts of the process were necessary to focus in? Which can now be let go? Which do you have to hold onto in order to maintain this focus?”
Tuning into the right level of awareness is one process; staying there is another. When you learn how to maintain your sense of stillness, try to keep it going in all situations. What do you discover gets in the way? Is it your own resistance to disturbances? Can you make your stillness so porous that disturbances can go through without running into anything, without knocking your center off balance?
As you get more and more absorbed in exploring these issues, concentration becomes less a battle against disturbance and more an opportunity for inner exploration. And without even thinking about them, you’re developing the four bases of success: the desire to understand things, the persistence that keeps after your exploration, the close attention you’re paying to cause and effect, and the ingenuity you’re putting into framing the questions you ask.
All these qualities contribute to concentration, help it get settled, get solid, get clear.
At the same time, they foster discernment. The Buddha once said that the test for a person’s discernment is how he or she frames a question and tries to answer it. Thus to foster discernment, you can’t simply stick to pre-set directions in your meditation.
You have to give yourself practice in framing questions and testing the karma of those questions by looking for their results.
