My dear Sonam,
Thank you for your kind letter, I was very happy to hear about your retreat. Regarding your health issue, there are several things to do.
You should have the Prajnaparamita Sutra read for you. This can be done by the Lama Gyupa monks here at Kopan, or even better, by the nuns at Kopan Nunnery. You can email Kopan directly to arrange this and they will let you know the cost.
You also need to take a long-life initiation, which you can request from Geshe Ngawang Drakpa of the San Francisco center. He can decide which one to bestow. Also request Geshe-la to read Zungdu [Collection of Dharanis] and dedicate this for your benefit. When you request this, it is important to make an appropriate offering.
I may be giving a long-life initiation in the Bay area in late February or March. My schedule is not yet confirmed, so please keep checking the FPMT website.
Take the Tibetan medicine khyung nga: three pills per day for two days. Holly will arrange to have this medicine sent to you.
The puja chab trü also needs to be performed for you. This is normally done by a Lama Gyupa monk. Request Donyo, who runs the Gyuto Monastery in San Jose, to arrange this for you.
You also need to have the mantra water of Vajra Armor. First, get a large bottle or jar of water, with a wide mouth so you can blow into it. Do the practice and recite one mala of the Vajra Armor mantra, then blow into the water. While you are reciting the mantra, visualize that Vajra Armor is sitting above the water and nectar beams flow from his heart into the water, making it very powerful, so when you drink the water it purifies all disease, defilements, negative karma, sickness and spirit harm collected since beginningless time. You can do more than one mala, but one mala is the minimum. After each mala, blow into the water, blessing it and making it so powerful to purify.
Then each morning before breakfast, as well as before lunch, mid-afternoon and before bedtime, take a few spoonfuls of the water and drink. Keep blessing the water, refilling the container and so on.
I have also sent a protection for you to wear.
With love and prayers...
