Meditation can be an aid to control thinking, but it can also prolong the thought process itself because it creates in the mind the idea that "I am now meditating", it creates a "meditator" that gets identified with. Any kind of identification with thought is just more thought. At best, most meditations can help you to stop thoughts momentarily, but once the technique stops thoughts tend to be just as frequent.
The key to stopping thoughts is to simply observe them without judgment, without trying to get rid of them or to hang on to them. Trying to stop thoughts is like standing on a board and trying to lift yourself off the ground. The very effort of trying keeps thoughts in place becuase the effort itself employs thinking. So instead, simply sit down with eyes closed and observe them closely - watch them come and go again all by themselves. By letting them come and go there eventually arises the realization that what you are is not dependent on thinking; the observing of thoughts/mind comes from silence itself. That silence is your true nature, your essence, and once you recognize your true nature thought stream tends to quiet down all by itself.
