I checked for a long time regarding your health. This is my advice:
1. You should do White Heruka retreat. (Of course, it is up to you whether you do this or not.)
2. Each month the students should recite the Golden Light Sutra at least once. They should dedicate it to your long life. The dedication can also include to prevent wars and fighting in the world today, natural disasters such as hurricanes and fires etc, difficulties in Burma, Pakistan, in essence, for world peace.
3. The Kangyur needs to be recited.
