Chola king Kalmashapadan was much annoyed as he did not have a progeny even after long years of marriage. He felt that he would have none to continue his services to the Lord. He appealed to Sage Agasthya who advised him to go to Tiruvarankulam and worship the Shivalinga. The king came to this place but could not find the Shivalinga and sought the help of shepherds. They told him that puja materials carried by people through that way fell down at a particular spot. The king dug the spot when the earth began to bleed. The Shivalinga was there. The king attempted to kill himself for injuring the Lord. The Lord appeared, prevented the king from the attempt and offered darshan with Mother Parvathi in His wedding form. The temple was built here then. The event took place on a Pooram star day. The King was also gifted with a male child.
There was a golden palm tree on the outer corridor of the temple yielding golden fruits. It is said that the temple was built with the sale proceeds of the golden fruit. There is a pillar now. The temple was built before the 12th century and renovated by Cholas and Pandyas. As the holy spring came from the head of Hara, it is called Hara theertham. The place came to be known as Tiru Haran Kulam–Tiruvarnkulam.
The residing deity Lord Hari Theertheswarar is worshipped as the family deity of people residing in places around 150 kilometer of the temple. Mother Perianayaki graces with four hands facing south. It is said that Mother Goddess was born to one belonging to Kattudayan Chettiar lineage. Based on this belief, women of this community regard Lord Shiva as their son–in–law and worship Him covering their head with Sari – Mukkadu.
Poora Theertham is a spring in the world of Agni. There are Shiva theertha, Naga theertha, Gnanabrahmma theertha, Indira theertha, Sri theertha, Skanda theertha and Guru theertha – seven theerthas in the Poora star region. The temple is dedicated to Pooram star. Those born in this star are advised to visit the temple as often as they could, on their annual star day, monthly star days, wedding days and Aadi Pooram day.
