My most dear, most kind, most precious wish-fulfilling one,
I hope you are feeling better or getting better. I did some checking, and this is my advice.
If you can, do Vajrasattva meditation with 200,000 mantras. Do this when you can, along with the four opponent powers etc.
Also do 100,000 prostrations to the Thirty-five Confession Buddhas. If you can’t do the physical prostrations, then do it with your hands in the mudra of prostration. The reality is that every merit field is a manifestation of the root guru.
Visualize [the merit field] as large as you can, imagine it covering the whole earth. Beams are emitted from the merit field purifying all the negative karma committed with the body, speech and mind since beginningless time, and especially the negative karma which has been committed with the guru, as this is the heaviest.
At the end of each mala think that all your negative karmas, which are in the form of darkness within you, are immediately gone, when sunbeams are emitted from the merit field to you. Then you can think that the six-realm sentient beings are purified. This is very important purification.
You also need to liberate fifteen animals. If you are liberating insects, it could be many more. Generally, if you can buy many insects that is good, however, because the number is fifteen that usually means larger animals.
I am planning to buy some land in south India to build a chicken retirement home. I want to liberate them from the commercial chicken farms where they are treated extremely badly and then killed when they are of no use.
With love and prayers ...
