Legend
During Treta Yuga, Bali was ruling the kingdom of the three worlds in a righteous way. The demons Mali, Sumali and others sought the help of Bali to fight against the devas. Bali simply declined to help them. The demons fought alone were defeated by the Devas. They came again to Bali for help which he obliged this time. Bali won the war but was afflicted with the Sin of Fighting the Devas without a just cause. He came to this place for relief and performed penance to the Lord. Pleased with his penance, Perumal appeared before Bali and granted darshan in Varaha Rupa. Sage Kuni and his daughter performed penance to Lord Narayana to reach Svarga or heaven. Kuni alone reached but not the daughter. Maharshi Narada told the young girl that she could not reach Svarga as she was not married. He requested other sages to marry her. Kalava Maharshi married her and had 360 girl children. He performed penance to Lord Narayana begging Him to marry his daughters. Narayana did not come. A Brahmachari, an unmarried youth came one day there saying that he was on a pilgrimage. As he was very handsome as Nayarana, the sage requested him to marry his daughters. He agreed and married one each day, on the 360 days of the Hindu Calendar. On the last day, He showed who he really was. He was none but Narayana in the form of Varaha. The Lord the merged all the 360 daughters into Akilavalli Thayar who is seated in the left lap of Varaha Swamy. As Perumal seated Akilavalli in His Left Lap The place was originally known as Tiruvidavandhai which later changed as Tiruvidandhai.
Sri Nithyakalyana Mahatyam
Sage Markandeya and King Mahabali visited this holy place. Pilgrims visit for the blessings of Lord Nithyakalyana Perumal. Those who want to get married offer two garlands. After Puja, the priest gives back one of the garlands. The person wears that garland and does Pradakshinam around the Temple. Later they bring the Garland home. This pooja blesses one to have early and happy married life. After marriage as a thanksgiving gesture, the couple revisit the Temple and offer flower garlands to the Lord. They carefully bring the old garlands from home and offer them to them to the divine tree in this temple, which is a Punnai Tree behind the Temple. People without children also worship this God and it is believed that the couple will be blessed by a child at the earliest.
