My most dear, most kind, most precious, wish-fulfilling one,
Thank you very much for your message. It is not known yet in the West, but this is caused by spirits, which enter and use that person’s mind to kill them. For many people who are suicidal, it's caused by spirits influencing the mind, so then they do many things.
Usually there is some problem of attachment or self-cherishing thought—that person wants to get something but doesn’t get it, then along with that, there is spirit harm. Then the thought comes to commit suicide or there is paranoia, so these things happen. Also they can hear sounds. There is nothing there in reality, but still they hear the sound of another person. This is all to do with spirits.
I checked and your relative needs to have Most Secret Hayagriva torma pills that are crushed up and then burned, and then they should smell the smoke when it starts to happen.
Also, the Kangyur needs to be read for them. It’s best if that is done by Ganden Shartse Monastery in South India. If you can't afford to sponsor this, it could be checked if there are others who also need the Kangyur recited and they could help you. This is something you would need to discuss with the monastery.
This is what came out in my observation. I am also making prayers for her.
With much love and prayers ...
