The benefits of reciting the Compassion Buddha mantra are infinite, like the limitless sky.
Even if you don’t have much intellectual understanding of Dharma, even if the only thing you know is OM MANI PADME HUM, still the happiest life is one lived with an attitude free of the eight worldly concerns. If you live your life with the pure attitude free of attachment clinging to this life and simply spend your life chanting OM MANI PADME HUM-this six-syllable mantra that is the essence of all Dharma-that’s the purest Dharma.
When one who recites ten malas a day goes swimming, whether in a river, an ocean or some other body of water, the water that touches that person’s body gets blessed.
It is said that up to seven generations of that person’s descendents won’t get reborn in the lower realms. The reason for this is that due to the power of mantra, the body is blessed by the person reciting the mantra and visualizing their body in form of the holy body of Chenrezig. Therefore, the body becomes so powerful, so blessed that this affects the consciousness up to seven generations and has the effect that if one dies with a non-virtuous thought, one is not reborn in a lower realm.
When such a person walks down a road and the wind touches his or her body and then goes on to touch insects, their negative karma gets purified and causes them to have a good rebirth. Similarly, when such a person does massage or otherwise touches others’ bodies, those people’s negative karma also gets purified.
