Use of TwiceBorn Threads by Ksathiriya Nadars:

Taking upto partial Vegetarianism or at time Total Vegetarianism, abstaining from liquor habits and Sanskritization ( Sanskritization does not meant anything such as learning Sanskrit or becoming Brahmins but it means in other simple words, climbing the ladder of Jati hierachy) go hand in hand across India whenever a lower caste community group prefer to take a course for upward mobility and community progress in totality. The twice-born castes ( those who wore sacred threads and were desecended from a "high order Gotra" or who prefer to assign to some of the royal lineage “Soorya Vamsam”) considered themselves purer and there was always exhibited social/moral pressure to demonstrate that with diet restrictions - e.g. hardcore goat-eating Kashmiri brahmins use hing instead of garlic in even mutton recipes.

While India has a larger number of thread-wearing castes as a percentage of the population – Brahmans take up sacred thread as part of their routine life after first initiation, whereas Kshatriyas and Vaishyas ( typically descendant of family members of Kingdom / thakurs, banias etc) and many of them, especially womenfolk, prefer partial vegetarian diets on selected period or selected days in a week/month. The Brahmins represent the permenant sacred thread-wearers, thus a smaller percentage of twice-born castes in the population and a therefore a smaller percentage of pure vegetarians.

Use of Twice-born thread by few communities are peculiar and has rich traditional history. One such community is potter community who make legendry horses/elephants for ayyanar temples. However other Kshathiriya Community having royal lineage especially Nadar tribe take twice-born thread ceremonies on special occasions such as confronting enemies in battled field, special worship and prayer for their Family Deities (Kuladeivam) or their lineage Amman Deties (Mutharamman or Malai amman, Kaaliamman, etc.) and during berieving of their parents/ forefathers etc.

While Nadars reaffirmed their claim to Kshathiriya status they ensured they attained a special status in Tamil Nadu by selectively adopting to wear the “sacred thread” of the “twice-born” , which elsewhere is generally thought to be reserved for pure higher castes, and they frequently used this ceremony to exhibit their prime life duties when necessity arises for doing last rites for their departed kith and kin and to act as unofficial guardian priests of the powerful village almighty Amman temples.(Kaliamman or Muth Aara (malai) amman also commonly known as Muthalamman, MuthuMalai amman or simply Malai amman in interior villages) This hereditary task enhances their standing in the community and gives them the enormous advantage of a share in the belief, self-confidence and pride to claim to higher level in social strata.
