This mantra taught by Buddha, the Stainless Pinnacle Lotus mantra, if it goes on the body, purifies 10,000 eons of negative karma. So this is very good to put on the head; this is how it is used.
It has many other benefits, such as bringing success and healing.
If a fully ordained monk has broken all four root vows and has been born in hell, thinking of that person and reciting this mantra has the power to liberate that person from hell and bring them a higher rebirth.
