Vaishnavism

While both the Vadagalais and Thengalais share a common religious origin and faith and also adhere to their own school of thought, neither of them condemns or rejects the sacred character of the other cult but there's an on going vicious fight between the two groups for nearly 200 years

Differences arose among Vaishnavites by about the 14th century as to the form of worship which by now has taken not so good turn!
