[Tamohara dasa ADMIN.]

SB 4.8.54 Purport:
Those who are not actually in the line of acaryas, or who personally have no knowledge of how to act in the role of acarya, unnecessarily criticize the activities of the ISKCON movement in countries outside of India. The fact is that such critics cannot do anything personally to spread Krsna consciousness. If someone does go and preach, taking all risks and allowing all considerations for time and place, it might be that there are changes in the manner of worship, but that is not at all faulty according to sastra. Srimad Viraraghava Acarya, an acarya in the disciplic succession of the Ramanuja-sampradaya, has remarked in his commentary that candalas, or conditioned souls who are born in lower than sudra families, can also be initiated according to circumstances. The formalities may be slightly changed here and there to make them Vaisnavas.
