Broadcast spiritual sounds to keep corruption out

In modernized human society there are great advancements of material science, and they have invented the radio to distribute sound in the air. So instead of vibrating some nuisance sound for sense enjoyment, if the state arranges to distribute transcendental sound by resounding the holy name, fame and activities of the Lord, as they are authorized in the Bhagavad-gita or Srimad-Bhagavatam, then a favorable condition will be created, the principles of religion in the world will be reestablished, and thus the executive heads, who are so anxious to drive away corruption from the world, will be successful. Nothing is bad if properly used for the service of the Lord.
