My most dear, most kind, most precious, wish-fulfilling one,
Thank you very much for your kind letter.
It comes out for you to recite the sutra Entering the Great City of Vaishali, the painkiller sutra, from the Buddha’s teachings. You should recite this sutra, but if you can't then maybe someone else can recite it in front of you. How many times you recite it depends on you. Do this until the pain goes down, which depends, I guess, on your karma. Maybe read it four times and if there is no change then do it another four times.
Of course, the main purpose is to achieve enlightenment for sentient beings, but in the meantime, to stop your sickness. You have to recite it out loud.
It comes out best for you to go to a Chinese doctor a few times, for example, for acupuncture.
You also need to recite two mantras:
Recite these for some time. I am making prayers also.
I hope to see you soon. Thank you very much for your service to the center, to His Holiness the Dalai Lama, Lama Yeshe, and to myself.
What makes your life most meaningful is meditation on the lamrim, and to live your life with bodhicitta motivation. This is the best.
With much love and prayers ...
