Mostly as a hobby, and I'm gonna have to study a lot in order to become a full fledged cleanser. Why you asked?
Because my sister was almost tempted to commit suicide by ghost children in the form of dolls. we live near a Victorian house that was once a hospital (ppl around our neighborhood say it used to be a morgue, but I don't see any evidence.) and I want to help ppl who are falling victims to bound spirits.
I will still do what I do, but I'll be adding cleansing as a hobby.
Why not an exorcist?
Cause you're damaging the spirit, and forcing it to pass on. Cleansing it would bring the spirit at peace.
And if I do have the time, I could be able to cleans our house and our neighbors house.
Edit: I'll tell you my tale of the cleansing of my domain when the deed is done.
