1. How there can be peace in the world

    The example is set by the Supreme Personality of Godhead that human civilization will advance only on the basis of brahminical culture and cow protection. As soon as there is falldown from brahminical culture, and as soon as there is discrepancy in the protection of cows, there will be no more peace in the world. Therefore He specifically said, go-brahmana-hitaya ca. This Krsna consciousness movement is for the protection of brahminical culture and cows. Then automatically the peace of the world will come, if two things are done.
