This peace formula for the world is given in the Bhagavad-gita (5.29). When people know that the Supreme Lord, Krsna, is the supreme enjoyer, the supreme proprietor and the most intimate well-wishing friend of all living entities, peace and prosperity will ensue all over the world. Unfortunately, the conditioned souls, being placed into illusion by the external energy of the Lord, want to fight with one another, and therefore peace is disturbed. The first prerequisite for peace is that all the wealth presented by Sri, the goddess of fortune, be offered to the Supreme Personality of Godhead. Everyone should give up his false proprietorship over worldly possessions and offer everything to Krsna. This is the teaching of the Krsna consciousness movement.
