Sri Vinayaka in the temple is praised as Lord Periyanai Ganapathy and Muruga as Lord Shanmuga.

Lord offers mental peace to devotees and release from sins of the past birth.  There will be no worries about children under adverse planetary situations.  Any obstacle in the undertakings of the devotees would disappear.  Building plans will go off without problems as this is the place where Vasthu Sastra was born.  As planet Shukra – Venus was relieved of his curse here, no obstacle would occur in marriage talks.

Tirukovilur has the reputation where the wedding of the daughters of noted Tamil philanthropist and king Pari Vallal, Angavai and Sangavai were celebrated with efforts of great poetess Avvaiyar and poet Kabilar.  The bridegroom was Deiveekan the king of the place.  The names linked to this wedding are the names of the villages surrounding Tirukovilur.  This is the place where noble and reputed Tamil poet Kabilar lived and placed his life to rest undertaking a fast.  The rock on which he was sitting facing north is even now known as Kabilar Hill.

Lord Muruga of this temple is praised in the Tirupugazh hymns of Arunagiriar,  This is also the birth place of Meiporul Nayanar and Narasinga Munaiarayar

Mother Vishnu Durga with Her eight hands in the prakara is so merciful in her look with eyes pouring all blessings to devotees, ensuring removal of obstacles in wedding and job efforts.  Rahukala puja lamps on lime cups are offered in the shrine on Tuesdays (between 3.00-4.30 p.m.), on Fridays (between 10.30-12.00 a.m.) and Sundays between 4.30-6.00 p.m.

When Saint Sundarar and Cheraman were proceeding to Mount Kailash through sky, Avvaiyar was performing puja to Lord.  She was hastening to complete the pujas as she also wanted to reach Mount Kailash, the abode of Lord Shiva.  Lord Vinayaka appeared before her and advised her not to be hasty.  Avvaiyar performed Ganapathi Puja chanting her noted Vinayagar Agaval and completed the puja patiently.  Lord Vinayaka took the Vishwarupa – covering both earth and heaven, took Avvayar and left her at Kailash before Sundarar and Cheraman reached the destination.  As He took a huge form, Vinayaka is praised as Peria Yanai-huge elephant.

Lord Shanmuga wanted to perform Shiva Puaja to cleanse Himself of the sin of destroying the demons.  Ambica showed the place where the Vel fell from Her hands.  Hence the place is known Tiru Kai Vel – Kai-hand and Vel a weapon.   Muruga performed His puja here and is praised by Arunagiriar in his Tirupugazh hymns.

It so happened that the world became dark when Mother Parvathi covered the eyes of Lord Shiva which are but Sun and Moon in a play.  The darkness took the form of a demon.  Andhaka means darkness and also ignorance.  Life becomes dark due to ignorance.  Lord Shiva struck the Andhaka-darkness giant on his head with a club in His hand. The head of the demon began to bleed.  Every drop of blood that fell on earth grew into a demon and war continued.  Mother Parvathi prevented the blood from falling down by collecting it in a bowl.  The blood that fell down became 8 vertical and 8 horizontal lines crosswise and thus made 64 squares.  With His power, Lord Shiva created 64 Bhairavas for each square and prevented further production of demons and blessed the Devas in the celestial world.  This later came to known as Vasthu Shanti Puja for Bhairavas.  This also personifies the destruction of ignorance leading to enlightenment.
