Once in a while I find a great article that explains meditation in a simple way. Dr. Lisa Keating does a fine job on why meditation can improve mental and physical health. Some excerpts from the article:
Typically, people begin practicing meditation much like I did: Looking for more emotional balance, to cope with illness, or to enhance overall health and well-being. Some people are searching for how to feel “more present” or “awakened” in life.
While it may sound too simple to be true, just 20 minutes of meditation a day is linked to dramatic improvements in emotional and physical health.
Brain scans are beginning to show that meditation improves brain functioning. Research indicates that those who practice meditation regularly heal quicker from illnesses and surgeries, improve concentration, and feel calmer and happier.
