Dear Shri Nara,
Apart from the doctrinal differences between the two "kalais", thereis a rather widespread view that one of the two Kalais represents, people fromthe lower castes who converted to vaishnavism as also brahmin status whereasthe other kalai represents original (smartha) brahmins who converted tovaishnavism and visishtadvaita. I have heard this from one Iyengar sourceitself. Though you had, on an earlier occasion, rebutted the legend of Ramanujaclimbing the gopuram and calling upon all and sundry to convert, etc., my pointis, is there any possibility of lower castes having gained acceptance into thevaishnavite brahmin group?
Looking at the differences even now practised among christians, muslims etc.,based on pre-conversion caste status, it looks to me that the reason for suchdeep-rooted differences between the two "kalais" could not have beensimple philosophical disputes but has to be one of caste-based prejudices.
Lets get one thing clear - Never in history has there been a caste conversion & no King has ever ordered such conversions!! Brahmin control over the Kings were total, so our ancestors maintained complete exclusivity.
Infact as and when Brahmins moved away to other religions, they were not identified with Brahmins there after. For eg. Lingayats in Karnataka were orginally Brahmins, & when they moved away/started following Basavanna, they were no longer identified as Brahmins. But you can see many Lingayats will say they were originally Brahmins.
So if you read my earlier posts – Brahmins are a separate race – mix of Romans + Greeks + Jews+ Dravidians. The Alexander soldiers took the local dravidians mostly the dravidian royalty as their wives. After the initial intermix, the Brahmins have maintained absolute exclusivity to this day. Because they took the dravidians as local wives, you will find approx 50% fair skinned & 50% Brown skinned in all Brahmin sects & sub sects.
So how did theThankalais & Vadakalais orignate. There were 3 migrations of Brahmins from Karnataka – Trojan Kingdoms – Kingdom of Ravana & Kauravas !
First (small) migration happened prior to the Ramayana war from the Trojan empire to Tamil Nadu Kingdoms & they were performing the rituals, poojas working for these Kings.
Second (Major) migration happened after the Ramayana war, so Brahmins from Troy/Lanka migrated to Narasimhavarman’s kingdom & settled in Kanchi. Kanchi - capital of Narasimhavarman kingdom is also known as Brahmeespuram & controlled all Vedic studies, philosophyetc.. in all through to this day !
Third (Major) migration happened after the Mahabharata war from the Karnatic (Kauravas/Karna) Kingdom to the Pandian King. These Brahmins carried the Carnatic music with them.
Thats why - you will see some Brahmin families with carnatic music and some only restrict to study of Vedas !!
Some of the people from this
first migration aligned with their Kings & they started exclusively identifying with Narasimha – Vishnu God – these are theThenkalais & hence they control a large portion of the temples.
After the Second/ third migration, some of the Brahmins who embraced Vaishavism along with Ramanujam who was an Iyer Vadama himself were called “Vadakalais”!
This came up in an earlier discussion with Brahmins worshipping Madura Kali Temple at Sirivachur where the priests are NBs but you find a lot of madisar wearing Brahmins coming here. Not sure if people know that ShankaraCharya Periaval’s family diety is Sirivachur MaduraKaliamman temple !!. Kannagi before she burns down Madurai, tells – spare the brahmins, innocents ... so the brahmins who were spared by Kannagi worship her to this day. The NB priests are the descendants of the Sherperd family where Kannagi & Kovalan stayed prior to the incident.
So again there was/is never any converts into Brahmins. In short, the Brahmin exclusivity was so high, and even if some of the NBs had converted to Brahmins (I dont agree this ever happened becos there are no written inscriptions nor any Sanskrit texts talking about such conversions, but lets assume based on others assertion) during Ramanujam's time, they were NO longer identified as Brahmins after Ramanujam similar to what happened after Basavanna.
