A.      It allows you to concentrate on one peaceful sound

 Mantra is a Sanskrit word which literally translates to “instrument of the mind.” From scattered thought and outward focus, mantras lead the mind to stillness and inner focus. Concentrating on one thought or on a phrase that doesn’t evoke strong emotions is a great start to achieve inner peace. Repeating the mantra will then prevent distracting thoughts and ideas from popping up. The repetition will gradually slip the mind into a state of thoughtlessness which is better than forcing the mind suddenly to do so.
