I've practiced meditation for many years, although I've neglected it a bit recently.
I sit in a comfy chair or couch, go through some simple relaxation techniques (tensing then relaxing each muscle group individually), then some rhythmic breathing followed by about five minutes of total silence letting my mind be free of thought.
The whole thing takes about 10 minutes and one of the fringe benefits is that the last five minutes seems to last a long time. It's more difficult to free your mind of thoughts than most people realize. But then, throughout the day when I start to feel rushed or stressed, I remind myself that I have plenty of time because five minutes is a really long time!
If you haven't tried it, don't be intimidated. There are some really simple techniques to get you started; you don't have to follow a complex routine or have special accessories or positions. And I have experienced benefits with even just 5-10 minutes a day. But once you experience the benefits, you'll probably want to do it more frequently or longer. It's a great way to fill up those 5 or 10 minute gaps in your day between activities, such as waiting in the doctor's office, for example.
