I think the most important thing is to know why one meditates; this is what gives the quality of the meditation and makes it of one order or another.
      You may meditate to open yourself to the divine Force, you may meditate to reject the ordinary consciousness, you may meditate to enter the depths of your being, you may meditate to learn how to give yourself integrally; you may meditate for all kinds of things. You may meditate to enter into peace and calm and silence -this is what people generally do, but without much success. But you may also meditate to receive the Force of transformation, to discover the points to be transformed, to trace out the line of progress. And then you may also meditate for very practical reasons: when you have a difficulty to clear up, a solution to find, when you want help in some action or other. You may meditate for that too.
      I think everyone has his own mode of meditation. But if one wants the meditation to be dynamic, one must have an aspiration for progress and the meditation must be done to help and fulfil this aspiration for progress. Then it becomes dynamic.
