Meditation, and mindfulness practices in general, are scientifically proven antidotes to anxiety and stress, as they are about focusing the mind on what is rather than allowing the anxiety or stress itself to take over, and lead the mind into labyrinths of self-judgment, comparison, regret and other rumination.
So do any of these forms of meditation achieve their putative benefits? There are two ways to answer this question. The first is to examine the scientific evidence and the second is to consider subjective accounts from the many practitioners. Each perspective points in a slightly different direction; they are both explored in Part II: The Evidence.
