….Reciting the Compassion Buddha mantra just once completely purifies the four defeats of breaking the four root vows of self-liberation and the five uninterrupted negative karmas1.
It is also mentioned in the tantras that by reciting this mantra you achieve the four qualities of being born in the Amitabha Buddha pure land and other pure lands; at the time of death, seeing Buddha and lights appearing in the sky; the devas making you offerings; and never being reborn in the hell, hungry ghost or animals realms. You will be reborn in the pure land of Buddha or as a happy transmigratory being.
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.
Thus, when a person who has recited ten malas of OM MANI PADME HUM a day goes into a river or an ocean, the water that touches the person’s body gets blessed, and this blessed water then purifies all the billions and billions of sentient beings in the water. So it’s unbelievably beneficial; this person saves the animals in that water from the most unbelievable suffering of the lower realms.
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….
