1. Mlecchas and yavanas becoming nice Vaisnavas

    By engagement in the service of Vasudeva, one very quickly renounces material life. The members of the Krsna consciousness movement, for example, being engaged in vasudeva-bhakti, very quickly come to the stage of being nice Vaisnavas, so much so that people are surprised that mlecchas and yavanas are able to come to this stage. This is possible by vasudeva-bhakti.
