If you go in a house ghostly-haunted, if you chant Hare Krsna mantra they'll go away. They cannot tolerate. In my life there was several incidences like that. In my household life, I was doing business in Lucknow. So there was one house, very big house, worth thousands of rupees' rent, but it was ghostly haunted. So nobody would take that house. I took it at two hundred
rupees, [laughter] and very big house. All the servants, they complained, "Sir, there is ghost." So I was chanting. He was living in several spots, especially on the gate side. But I would chant Hare Krsna, and I was saved. Everyone was saved.

And, say, in 1969 I was guest in the house of John Lennon in London. So there was a ghost. It was a big plot. There was a guesthouse. So they complained, "Sir, here is ghost." So I advised them to chant Hare Krsna, and the ghost went away. Yes. This is fact. When there is Hare Krsna chanting, these ghostly, demonic living entities, they'll not be able to stay there.
They'll go away.
