My very dear Ven. Lindsey,
According to my observation, this is what came out very beneficial for you to do:

1. Liberate 500 animals. You can do more than this, but this is the minimum. Perform the animal liberations according to the instructions I have given, where you take the animals around holy objects, and bless them with mantras and blessed water. The main thing is to liberate animals that would normally be killed; in this way you are saving their lives. You can do this at the center so others can join in.

Dedicate this not only to your own long life, but also to the long life of His Holiness the Dalai Lama and all holy beings in this world who benefit others. Also dedicate it to the long life of the Sangha, who live in pure morality.

2. Recite the very long Chenrezig Dharani (longest Chenrezig mantra) every day. Dedicate this to being completely healed from the cancer or to being reborn in a pure land.

3. Recite the Heart Sutra 130 times.

4. Do Medicine Buddha puja once a month at least.

I am also making prayers for you. Also, the Sangha at my house are dedicating animal liberations to you and long-life tsa-tsas, which they make each day.

With much love and prayers...
