Meditation is simply a question of being. You just quietly sit, your body still, your speech silent, your mind at ease, and allow thoughts to come and go, without letting them play havoc on you. If you need something to do, then watch the breathing. This is a very simple process. When you are breathing out, know that you are breathing out. When you breath in, know that you are breathing in, without supplying any kind of extra commentary or internalized mental gossip.
