EVERYONE has any and all psychic abilities but dont know how to 'trigger' them. ANYONE can do magick but doesnt know it yet
Meditation opens those areas of the mind, triggers them, if you will and brings the latent, unused talents/powers/abilities to life.
Some people have triggered them by accident, like going into a 'dwaal' or 'trance' while plodding along on long walks, taking long drives or during those instances where you 'stare into space' and people ask you, "Where were you?" - all various forms of purposeful or acidental meditation that wittingly or unwittingly, open certain areas of the mind.
Some people are born with these areas already triggered.
Meditation can, and does, trigger the mind. Remember, thoughts are energy. You send out thoughts they will clash/meld with the energies around you. Meditation stills the mind, (or not, lol), and this allows the universal energies in and helps open the mind and the areas that 'control' supra-natural, (NOT a spelling mistake), abilities. If you are unable to still the mind but the attempts to do so are there, there is still a chance that just in the act of trying, the energies you send out will attract those same universal energies that 'trigger' psychic abilities.
Meditation is actually important in aiding/enhancing/opening psychic abilities.
