Meditation is the art of silencing the mind. When the mind is silent, concentration is increased and we feel inner peace. Meditation enables us to have a deeper understanding of our inner self. Through meditation we can gain a better understanding of our life’s purpose. Meditation is observing what's going on — both internally and externally — without necessarily reacting to it.

Just to put in another two cents on this topic

Meditation is the process
of peeling back the self
until pure awareness remains,
at which point awareness
can recognize itself as
Totality perceiving itself.

I've read an article about pain, that the more depression being experience the more our mind get stress and might lead to different illnesses. Meditation techniques really helps me a lot. This site really add a good insight about meditation and the benefits to our mind, body, social attitude and the greatness of being relieve from pain through meditation.

>>> Base on what I read, Learning meditation techniques to relieved from pain. The key shift is in turning toward pain, when all your life you’ve turned away from it. You give it your full attention you yield to it and, paradoxically, its hold on you diminishes. The majority of chronic pain patients in an eight weeks meditation course are able to reduce their medications and become more active. You open to emotional pain as well. As you meditate, the grip of your history loosens and you get a little saner, lighter, less entangled.
