By the regular performance of yajna, the equal distribution of wealth and the restriction of sense gratification, the entire world will be made peaceful and prosperous. As already mentioned, in this age of Kali the simple performance of sankirtana-yajna — the holding of festivals as initiated by the International Society for Krishna Consciousness — should be introduced in every town and village. Intelligent men should encourage the performance of sankirtana-yajna by their personal behavior. This means that they should follow the process of austerity by restricting themselves from illicit sex life, meat-eating, gambling and intoxication. If the intelligent men, or the brahmanas of society, would follow the rules and regulations, certainly the entire face of this present world, which is in such chaotic condition, would change, and people would be happy and prosperous.
