The spreading of the Hare Krsna maha-mantra in the West has become successful because the young people were not offenders. The youths who joined this movement were not very advanced as far as purity is concerned, nor were they very well educated in Vedic knowledge, but because they were not offenders, they could accept the importance of the Hare Krsna movement. We are now very happy to see that this movement is advancing more and more in the Western countries. We therefore conclude that the so-called mlecchas and yavanas of the Western countries are more purified than offensive Mayavadis or atheistic impersonalists.
