Yes, meditation is a natural ability that anyone can master. But, as with yoga, it means different things to different people. If you approach it primarily as a Way to relax that is what you will get out of it. And there is much data proving its value as such, particularly for professional athletes.
Some people approach meditation as a Way to en-lighten consciousness from the dead weight of egoic materialism, and that is what they get out of it. Think if it as the distinction between focusing on upper body when you work out as opposed to focusing on core.
We live in an age which mistakes Ego for Self. This leads to various spiritual maladies intrinsic to misassociation of what is to what is not. These maladies restrict what would otherwise be the free Flow of energy up the Jacob's ladder of the Chakras which even mainstream science is grudgingly beginning to admit do, indeed, exist.
Enlightment, via meditation, is a Way to en-lighten Consciousness from the dead weight of those maladies by opening up those clog points which restrict the serpentine ascension of kundalini. But, perhaps that is detail best put off until another time.
Meditation, with the goal of spiritual enlightenment, deprograms mind by training it to shut up and Just Listen for a Change instead of the incessant talk, talk, talk Ego has conditioned it to do.
