Dear Mary,
I checked for you regarding your condition, and the operation now comes out very good to do. Although it comes out very good to do it, before the operation it is good if you take a Highest Yoga Tantra initiation and do retreat, so you can do self-initiation. If you can’t do self-initiation, then do Lama Chöpa and tsog a few times within the retreat.

Previous advice from Rinpoche six months earlier:

I checked for you regarding your operation, and it is better for now not to have the operation. You need to recite Vajra Armor mantra. The minimum is half a mala a day, but it would be better if you could recite one mala a day. Every half mala blow on a bottle of water to bless it. Visualize the deity in front of you, surrounded by all the buddhas and bodhisattvas, who are sending light to the Vajra Armor deity’s heart. From the heart of the deity, light comes and enters you and you feel very blessed. All the karma of disease is purified for yourself and for all sentient beings. Then, all harm from spirits, etc, is purified. Focus on the area where the tumors are and feel this as extremely powerful purification.
