Magic is based on belief and visualization; following rituals, reciting certain words, etc. helps people believe that they can perform magic, but it's not necessary. Whether words like "om" have any special significance in the universe I don't know, the most I could imagine would be that if for thousands of years millions of people chanted that word with the belief that it was magical then every person who chants it taps into that thought energy attached to the word.
