You don't have to sit like the picture to the right to meditate.  In fact you can sit, stand, lie down or be any way you are comfortable.  Meditating is just concentrating on something and pondering it for a time.  Most people find paying attention to their breath a good way to start.  Breathing is natural and we all do it.  Breath in through the nose and out though the mouth.  Feel the air fill your lungs and your body become tight then exhale and your body relaxes a bit.  Don't try to control your breathing or you will end up dizzy.  If unpleasant thoughts intrude just go back to your breath and feeling that.  Don't scold yourself for thinking those thoughts, just go back to the breath.  Notice how your body feels as it is there.  Are you aware of your surroundings?  Do you feel the temparture of the room?  What are the sounds you hear?  Are they loud or soft?  Do you need to adjust your position?  Be aware of it all.

Start with this method for 5 minutes at a time and gradually add more time.  Believe me, 5 minutes seems forever when you first start.  You might add a burning candle to concentrate on or some "white noise" to shut out other bothersome noises.  A nice peaceful piece of music may help you to keep from wandering.  There is no wrong way to meditate.  As you learn to quiet your mind to stressfull things you will find that you enjoy your alone time to "turn off" for a while. 

Try a CD or tape from a bookstore to help you get going with your meditation experience.  There are some great Visualization or Grief Processing recordings that you can try.
