My very dear, most kind, most precious, most wish-fulfilling mother,
Thank you very much for your kind letter. I just arrived from Mongolia, where they did a 108 million Mani Retreat. There were more than 60 Westerners, mostly nuns, and many Mongolians, who did extremely well. They recited 108 million OM MANI PADME HUM mantras.
This is incredible, unbelievable purification, purifying negative karma collected from beginningless time. This is the way to collect most extensive merits up to enlightenment and particularly to purify many negative karmas, disease and problems. Many difficult things that are not easy to get rid of can be purified with this mantra, and particularly we can develop compassion for all living beings—numberless hell beings, numberless preta beings, numberless animals, numberless human beings, numberless suras, numberless asuras and numberless intermediate state beings. That compassion for all beings is what makes us achieve peerless happiness up to enlightenment, to be able to do perfect works for others.
Please continue your life with a good heart to others, as you already have. This is where all the satisfaction comes from.
With much love and prayers...
