Thank you very much for your kind letter. I am terribly sorry that it has taken such a long time to answer, due to my always traveling, not being very long in any place, and doing this for a long time.
I am sorry to hear of your brother’s condition of ringing in the ears. You should boil ginger in hot water, not cold but hot, then holding the ginger in both hands (as hot as can be tolerated), press it on his back at waist level. If he can do this again and again, this will stop the ringing in his ears.
At the __ center, Geshe-la can be requested to do Chab Trul puja for purification. This could be beneficial. Also, he can be requested to do one small puja, Giving Lu (body), using tsampa to make the dough in the shape of the body and giving it to the spirits, for them to not harm.
Also, you can chant Most Secret Hayagriva mantra. Find the picture for your brother and he can look at it while reciting the mantra. Visualize and make requests to purify disease, spirit harms, negative karma and obscurations. Visualize white light for purification, then chant the mantra with that visualization, half for purifying and half for generating the qualities of omniscience, compassion and power. Do this for half an hour, half for each visualization, or for one hour, or one mala each for purifying and generating qualities, if not, do half a mala for each, but try at least to do one mala.
I will also do a short puja for him.
With much love and prayers...
