Can the cleansing process be harmful for the ghosts?
Mrs Pratnicka performs it in a safe way for the ghosts too. We can not forget that we are still talking about human souls and not parasites. On the contrary. The purpose of the cleansing process is to help these lost souls who did not pass through death’s curtain. Mrs Pratnicka offers them the chance to enter “Heaven”, a place where they belonged to just after their death. If they use that chance depends solely on the ghost itself. He also can refuse and stay in the world of the living.
