Once upon a time saints and devas were tortured by a rakchasha called Anthakasuran. They requested Lord Shiva to save them. Lord Shiva told Lord Brahma to do a yaga at the banks of river Ganga. By the grace of Lord Shiva and Lord Brahma, a beautiful and intelligent human formed out of yaga fire. They named him as Pritheswaran. Lord Shiva blessed and gave him a bow. Lord Brahma gave a golden garland. With their blessings Pritheswaran fought against Anthakasuran and killed him. Saints and devas were happy. They thanked Lord Shiva and requested to bless Pritheswaran with marriage.

Lord Shiva blessed Pritheswaran to become the king of city Kasi and got him married to Kanabai, daughter of Kanabindu the head of Gandharvas. The people of Kasi lived happily under the rule of king Pritheswaran. The king had four sons and got them married to Gandharva females. The king and queen at their old age did meditation and attained mukthi. First son of Pritheswaran had two sons and two daughters and other sons had two sons each. They all got married to Gandharvas. First grandson of Pritheswaran, namely Vaidunga Devarayan came to rule. None of his brothers and sisters including him had children. During that period, Saint Kalavai from Himalayas visited the city kasi. Vaidunga met him and told him his sorrow of not having children. The saint suggested the royal family to visit the Saint Kalaikottu at the city of Kancheepuram. All of them went to Kancheepuram. There, Saint Kaikottu told them to pray to goddess Kamatchi every day. One day, in dreams of Vaidunga, the goddess told him to perform Puthra Kameti Yaga. Vaidunga conducted the yaga with the help of saints.From the yaga, a ghost came out and handed over a golden vessel full of holy food ('Aviunavu') to the saint kalaikottu. The saint divided the food into 24 parts. Wife of Vaidunga and the wives of his other brothers received two parts each to eat. Whereas the two sisters had four parts each.

After which Vaidunga and his brothers had two sons each and his sisters had four sons each. Thus they are the 24 great grand children of Pritheswaran. The saint told them to divide kancheepuram into 24 divisions, one for each of them and rule.
Vaidunga's and his brothers sons where categorized as 16 veedu people and his sisters sons were categorized as 8 veedu people. The saint also instructed that the people of same veedu category should not have marriage alliances among themselves.
