Question: If you hadn't thrown these spirits out, would they have left on their own?

Sri Chinmoy: Of their own accord, spirits do not decide to go. Once they have occupied a place, it is like a hostile force; they occupy a territory and one has to work very hard to get them out. I have done it in a few places. Some people pray to God and then God helps them.
