Meditation is a group of mental training techniques .You can use meditation to improve mental health and capacities, and also to help improve the physical health. Some of these techniques are very simple, so you can learn them from a book or an article; others require guidance by a qualified meditation teacher. You breathe regularly. You breathe in deep enough to get enough oxygen. When you breathe out, you relax your muscles so that your lungs are well emptied, but without straining.

In other techniques, the concentration is more relaxed so that foreign thoughts easily pop up. When these foreign thoughts are discovered, one stops these and goes back to the pure meditation in a relaxed manner. Thoughts coming up, will often be about things you have forgotten or suppressed, and allow you to rediscover hidden memory material. This rediscovery will have a psychotherapeutic effect.
