In New York, when we started this movement, so in the morning, at seven o'clock, we used to hold our class, and there was little sound. Immediately the tenants from upwards, they'll come down and complain. Sometimes they will call for police. And on the street, Second Avenue, there is always big, big trucks and motor cars going on, heavy sound. Then in your country the garbage carrier sound, the digging sound. So many sound they'll tolerate. And as soon, "Hare Kṛṣṇa," "Oh, it is intolerable." (laughter) This is demonic, the demonic. They'll not hear. Because that will do good to them by hearing, they'll not accept it.
It is practically experienced. I know that the ghost, if you go in a house ghostly haunted, if you chant Hare Kṛṣṇa 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. And I was... All the servants, they complained, "Sir, there is ghost." So I was chanting. He was living in several spots, especially on the gate side. So I could understand, but I would chant Hare Kṛṣṇa, and I was saved. Everyone was saved. There was... And, say, in 1969 I was guest in the house of John Lennon in London. So there was a ghost in... It was a big plot. There was a guest house. So they complained, "Sir, here is ghost." So I advised them to chant Hare Kṛṣṇa, and the ghost went away. Yes. This is fact. When there is Hare Kṛṣṇa chanting, these ghostly, demonic living entities, they'll not be able to stay there. They'll go away.
So two classes of men, demonic and divine. So divine nature has been explained in various ways from the very beginning. Now Kṛṣṇa is explaining about the demonic nature. The first characteristic of demonic nature is they do not know what should be the pravṛtti and what should be nivṛtti, proper and improper action. Improper action is mentioned here, beginning, that na śaucaṁ nāpi cācāraḥ (BG 16.7), not cleanliness. Cleanliness is essential. "Cleanliness is next to Godliness."
