The best type of meditation for getting control of intrusive thoughts is simply called sitting. In principle, sitting meditation is the simplest thing in the world. You just sit down and let all the thoughts drop from your mind. People who practice sitting can maintain a clear mind with no thoughts for minutes at a time or longer. Some experienced meditators can keep their minds clear of thoughts for hours wherever they are.
Sitting is an excellent technique to learn, because it is an instant antidepressant. If you are like most depressed meditators, as soon as the thoughts drop from your mind, your depression will fall away with them. It is a wonderful experience to obtain relief from your depression suddenly and completely, if only for a moment.
