As every meditator soon discovers, distraction is the normal condition of our minds. The goal is to come out of the trance of discursive thinking and to stop reflexively grasping at the pleasant and recoiling from the unpleasant, so that we can enjoy a mind undisturbed by worry, merely open like the sky, and effortlessly aware of the flow of experience in the present.
How to Meditate
The traditional goal of meditation is to arrive at a state of wellbeing that is imperturbable—or if perturbed, easily regained.
The near goal is to have an increasingly healthy mind—that is, to be moving one’s mind in the right direction.
Beginning meditators often think that they are able to concentrate on a single object, such as the breath, for minutes at a time, only to report after days or weeks of intensive practice that their attention is now carried away by thought every few seconds. This is actually progress. It takes a certain degree of concentration to even notice how distracted you are. Even if your life depended on it, you could not spend a full minute free of thought.
The eighth-century Buddhist adept Vimalamitra described three stages of mastery in meditation and how thinking appears in each.
One must be able to pay attention closely enough to glimpse what consciousness is like between thoughts—that is, prior to the arising of the next one. Consciousness does not feel like a self. Once one realizes this, the status of thoughts themselves, as transient expressions of consciousness, can be understood.
Meditators tend to have larger corpora collosa and hippocampi (in both hemispheres). The practice is also linked to increased gray matter thickness and cortical folding. Some of these differences are especially prominent in older practitioners, which suggests that meditation could protect against age-related thinning of the cortex.
One study found that an eight-week program of mindfulness meditation reduced the volume of the right basolateral amygdala, and these changes were correlated with a subjective decrease in stress. Another found that a full day of mindfulness practice (among trained meditators) reduced the expression of several genes that produce inflammation throughout the body, and this correlated with an improved response to social stress.
Five minutes of practice a day (for five weeks) increased left-sided baseline activity in the frontal cortex—a pattern that, as we saw in the discussion of the split brain, has been associated with positive emotions.
The goal of meditation is to uncover a form of well-being that is inherent to the nature of our minds. It must, therefore, be available in the context of ordinary sights, sounds, sensations, and even thoughts. Peak experiences are fine, but real freedom must be coincident with normal waking life.
