Recently a well regarded female lama in Nepal (whom I've met once) did several ceremonies to address my issue of spirit harm. They were quite successful and I've been doing a lot better. Recently the teacher who I learned the little house practice from told me that she no longer advises students to burn them, instead offering them without the burning. So far, I have done one without the burning and the results were not good. I will have to wait and see.
At this point, I am about 60% recovered from the serious mental illness that I had at the outset, which started in 2013. I am optimistic about continued improvement, but who knows if a full recovery is possible. My quality of life is significantly better and I'm hoping to be able to feel even better in the future.
