Nitya Kalyana Perumal (The lord who give boon for marriage)

Among the ten incarnations of Lord Mahavishnu, the third incarnation was in the form of Varaha, the Boar. The temple at Thiruvidanthai is dedicated to Lord Vishnu is the aspect of this incarnation. The Lord with the wild boar face is hailed as the embodiment of all wisdom and knowledge.

About the temple: The presiding deity of the temple is Laxmi Varaha Perumal and the utsavar is known as Nitya Kalyana Perumal. This is one of the 108 divyadesams of Sri Vaishnavas in Tondai naadu. The lord is found in a very unique posture of one leg on the ground, one above Adisheshan and his spouse, and Agilavalli thayaar on the left thigh. The Lord is said to have married all the 360 daughters of Sage Kaalava each day throughout the year and so the name ‘Nithya (daily) Kalyana( marriage) Perumal's. On the final day, the lord merged all of them into one called Agilavalli thayaar. Sthala Sayana Perumal temple, another Divya Desam at Thirukadalmallai is close by and both the temples can be covered at the same time.

Stala Purana: Once upon a time, there lived a sage, Kalava by name, who had 360 daughters. In those days, this temple town was so huge that it had 360 agraharams (main streets). Out of respect for the sage, residents in each street took up the task of bringing up each of the 360 daughters of the sage. When they grew up, the sage thought that it would be a Herculean task to get them all married suitably; praying fervently, he took refuge at the feet of Lord Adi Varaha. The most compassionate Lord Maha Vishnu assumed the form of a Brahmachari (bachelor), appeared in the first agraharam, proposed marriage to the first daughter, and then married her. When the newlyweds visited the temple of Lord Adi Varaha, they vanished mysteriously in the sanctum sanctorum. This was repeated to the rest of sage Kalava's daughters, day after day. The bewildered Maharshi wanted to know from God Himself the whereabouts of his daughters and sons-in-law. When he entered the sanctum sanctorum, Lord Varaha appeared before him, holding all the 360 daughters on His lap. The Lord merged all the 360 souls into the single soul of Goddess Lakshmi, making Her sit on His raised left thigh. The sage was greatly elated to be the father of Goddess Lakshmi Herself. As the marriage ceremony continued day after day for 360 days, the place came to be known as "Nithya Kalyana Puri" and the lord as "Nirthya Kalyana Perumal". Vaishnavite philosophy speaks of the whole of mankind as female and Lord Maha Vishnu as the only male "Purushothama". Eternal union of the souls with God brings salvation (Jeevatma merging with Paramatma). A great truth is driven home symbolically as the merger of the brides and the bridegroom.

Sri Adi Varaha helped Lord Srinivasa in Tirupathi, by giving the land. As to explain this, we can find a big white bindhi(big dot) in the chin of Lord Nithya Kalyana Perumal and the Goddess, as seen in the deities of Tirupathi.
