God has many names. It is not that you have to chant only "Krsna." No. If you have got any other name of God... Must be God's name. But they do not believe in God. Generally they think there is no God, or if there is God, God is dead. Something like that. And I don't think there is any definitive name in any other religious system. It is only in the Vedic system there is name. So anyway, if somebody thinks that "This Krsna is an Indian name. Why shall I chant 'Krsna'?" Well, you chant any other name, but it must be God's name. Then it will be effective.
