The root of the word meditation is similar to the root word for medical or medicate. In meditation, you pay attention to dimensions of yourself that are seldom observed or known - that is, your own deepest, inner levels. There is nothing strenuous or difficult about creating this inner attention.
Meditation does something that nothing else can do.
It introduces you to your Self. For if you don't know who you are, it is impossible to know anything else. Meditation is one of the most powerful techniques available to improve mental, emotional and physical well being. In meditation, you are fully alert, but the mind is not focused on the external world or events. In the process of meditation, we ask the mind to let go of it's tendencies to think, analyze, remember, solve problems, focus on events of the past or on the expectations of the future.
