I have seen this in Kanchi Varadaraja temple a few times. There are two groups of brahmins where one chants vedic mantras and the other tamil hymns. The sanskrit chanting group tries to suppress the tamil group by shouting out aloud. (It could also be the other way. But the body language suggests the former.) Why is there a fight between Tamil and Sanskrit? I have also heard some Tamil-Sanskrit rivalry in Chidambaram temple. What is the status of Tamil in our temples?
