It is beneficial to recite the mantra and blow upon meat that you are eating, and even on dead bodies or old bones, because it purifies karmic obscurations and allows the being to be reborn in a pure realm or in the upper realms. If you eat meat, you should make it beneficial for the animal that has been killed by reciting this powerful, purifying mantra before eating it and dedicating strongly for the animal to be transferred immediately from the lower realms to a pure realm or an upper realm and to never be born in the lower realms again.
Even if the animal or human being died hundreds or thousands of years ago and their consciousness is in the lower realms, reciting the mantra and blowing on their bones can transfer the consciousness to an upper realm or to a pure realm. We can also blow on water, sand, sand, or talcum powder and sprinkle it on the bones or skin of a dead animal or person. At the very least, it will shorten the duration of their suffering in the lower realms.
