WHAT IS THE DIFFERENCE BETWEEN SRIVAISHNAVAM AND SRIVAISHNAVISM

Answer: There is not much difference and mostly it can be said that its one and the same. The "ism" is added to many other sects such as Saivism, Pluralism, communism etc.  Persons who worship Sri Maha Vishnu (yes, you can say Vishnuism too) and follow Sri Ramanujas teachings are known as Srivaishnavites or Srivaishnavas. Interestingly if youre from Ahmedabad, Gujarat you might have heard about the very popular song  "Vaishnava Janato", sung by great Saint Sri Narsingh Mehta.
