Mantra is for some a path to meditation. It is the intentional repetition of a word or phrase for at least 108 times.
It is said that if you repeat a mantra 125,000 times you reach a critical mass of Omness and something wonderful happens. I’m not sure what sort of thing. It could be enlightenment. Or do you just win the lottery?
It takes weeks to say even aum so many times. The purpose behind prayer beads is to count the repeats. If you have an old rosary, you could use that (it’s said that Catholics got the idea from Hindus). Reciting the mantra so many times also takes commitment.
So I tried the exercise at this site as my first experiment. You can scroll through 125,000 aum symbols in a few moments and see what happens. I felt like I was getting soaked in aumness. See what happens for you!
