One of the greatest Hindu scholars of Vaishnava Tattvavada (Dvaita) philosophy, Madhvacharya, have come and resided in this temple many times.

He took even Chaturmasya deeksha here during this time he created Dhanda Teertha with his stick to quelch the thirst of a pregnant woman.

The festival also symbolises Hindu-Muslim unity in the region - the flag of the chariot is provided by Muslims; they take offerings from the temple and present to Allah in the mosques.

The temple is maintained and administered by the Hindu Religious and Endowment Board of the Government of Tamil Nadu.

The festival icon, Yagya Varahaswamy, as requested by Bhudevi displays the regular features of Vishnu with his conch and chakra in his hands.

[2] A unique tradition of the temple involves Hazrath Syed Sha Rahmathulla Shuttari, a revered Sufi saint who settled in Killai.

The Dargah trustee later sought assistance from a local tahsildar, Uppu Venkatarao, to demarcate the land, and in gratitude, 26 acres were permanently leased to the Sri Bhoo Varaha Swamy Temple Trust.

[4] An epigraph dated 1068 in the nearby Shiva temples indicates gifts by Virarajendra Chola (1063–1070 CE) to the Varaha shrine.

[citation needed] Another inscription dated at 1100 by Kulothunga Chola I (1070–1120 CE) indicates a gift of a village to the temple, where the presiding deity is referred as Varaha Alvar.

[5] The Zamindars of Udayarpalayam have contributed to the temple by offering costly jewels and commissioned additional structures, notably Udayavar Mandapam.

The 2 ft (0.61 m)-shaligrama stone image depicts the boar-faced Varaha standing in a victorious posture with his hands on his waist; the human body faces West, while the head is turned towards the South.

The utsavar (festival icon), Patharaavi, is made of panchaloha (a five-metal alloy) and is accompanied by two consorts as in most Vaishnava temples.

[6] The temple has two dvarapala (guarding deities) on both sides of the entrance of the central shrine made of panchaloha, one of which is commissioned during the modern times.

[7] The sixteen pillared hall is called Purushasuktha Mandapa and it is the place where the hymns of Purusha sukta are recited each day during sacred ablution of the presiding deity.

Udayarpalaya Mandapam, as indicated by its name was built during the period of zamindars and it houses the Kannadi Arai (room of glasses).

There are other shrines for Venugopala, Vishvaksena, Vedanta Desika, Thirumangai Alvar, Manavala Mamunigal, Kulanthai Amman and Tirukachi Nambi.

[citation needed] The temple bears the inscriptions in Telugu, one of which says the grants made by Sri Ranga Raya Deva of Vijayanagara.

The temple rituals are performed six times a day: Ushathkalam at 7 a.m., Kalasanthi at 8:00 a.m., Uchikalam at 12:00 p.m., Sayarakshai at 6:00 p.m., Irandamkalam at 7:00 p.m. and Ardha Jamam at 8:30 p.m. Each ritual has three steps: alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for both Sri Bhuvaraha Swamy Perumal and Sri Ambujavalli Thayar.

The inscriptions indicate patronage for the festivals to be conducted during the presence of Sun in 12 zodiac signs during various months of the year.
