The citizens of the state must give in charity up to fifty percent of their income for the purpose of creating a spiritual atmosphere in the state or in human society, both individually and collectively. They should preach the principles of Bhagavatam by (a) karma-yoga, or doing everything for the satisfaction of the Lord, (b) regular hearing of the Srimad-Bhagavatam from authorized persons or realized souls, (c) chanting of the glories of the Lord congregationally at home or at places of worship, (d) rendering all kinds of service to bhagavatas engaged in preaching Srimad-Bhagavatam and (e) residing in a place where the atmosphere is saturated with God consciousness. If the state is regulated by the above process, naturally there will be God consciousness everywhere.
