On Meditation
Research suggests that meditation can change brain structure, enhance mental abilities and work alongside traditional medicine to speed up healing.
Certainly, when I learned Transcendental Meditation through a formal course many years ago it was in some ways a life-changing experience, although I quickly moved away from the more cultish aspects of TM.
I don't entirely buy the claim that just a few minutes' daily meditation can make a difference between an anxious existence and a life of quiet contentment...but it helps.
