The below document is to be used solely to gain a better understanding of the Thenkalai Srivaishnavam principles. Specifically it’s not intended and must not be understood nor taken to show Vadakalai in an unfavourable light. Vadakalai Srivaishnavas may or may not agree with the principles ascribed to them in the below document, and may in fact have their own understandings for those principles they do agree with. Indeed, Sri Alkondavilli Govindacharya mentions in the article Tengalai and Vadagalai (July, 1912):
except that they have Vedāntāchārya and Ramya-jāmātṛ-muni as their respective pontiffs, the two divisions [Vadagalai and Tengalai], in ethnic, philosophic, ethic, and social affairs, constitute one Śrī-Vaishnava body.
