Meditation is a practice where an individual connects their mind to a mode of consciousness that is often ignored. Modern science is beginning to catch up to the benefits of meditating, it is being taught in certain schools to help train the mind to release and let go of tension, to allow clarity or peace to enter the mind.
Whilst meditation is often used by certain religions, the practice of meditation is not reserved to anyone of any particular faith or non-faith. The benefits of meditating are often debated and some will say it has no effect. I would say to that- even if it simply provides a space for the individual to rest their mind- in our often busy, over-stimulating and somewhat confusing daily regimes- that is a wonderful thing.
Meditation can be used to clear the mind and ease many health concerns, such as high blood pressure, depression, and anxiety. It may be done sitting, or in an active way—for instance, Buddhist monks involve awareness in their day-to-day activities as a form of mind-training. This never negates the need to seek out professional medical advice if it warrants it.
