Meditation is a mysterious method of self-restoration.
It involves “shutting” out the outside world, and by that means sensing the universal “presence” which is, incidentally, absolute perfect peace.
It is basically an existential “time-out”—a way to “come up for a breath of air” out of the noisy clutter of the world.
But don’t be afraid, there is nothing arcane or supernatural or creepy about the notion of taking a time-out. Ball players do it. Kids do it, when prompted by their parents. Heck, even your computer does it (and sometimes not when you want it to).
So, why not you?
A meditation can be as simple as taking a series of easy breaths, and slowly, gently counting to ten in your mind.
