“The chanting of Hare Krishna continues to vibrate the brain for several days.” We want to inject this transcendental poison into the heart of the Maya-serpent bitten people in general. Krishna Consciousness by the sound of Hare Krishna, it continues for a moment in the brain of the rascals, then certainly it will act in future to help them to become Krishna Consciousness. In the Bhagavad-gita (2.40) it is said: “Svalpam apy asya dharmasya trayate mahato bhayat.” Bhayat means fearfulness. Even a slight injection of this transcendental vibration can save one from the greatest danger.
