Reputation of the place:
There are six holy places equal to Kashi. Thiruvengadu is one among them. Here everything is three – the presiding deity, holy water and the holy tree. Of the nine planets, Thiruvengadu belongs to Mercury. This is one among the 51 Sakthi Peethas. Thiruvengadu has the pride of being sung by the Great Four, Thirugnanasambandar, Thirunavukkarasar (Appar), Sundarar and Manickavasagar. Of the 64 Murthas of Lord Shiva, the Agoramurthy form is here. Here the Lord performed Six dances. This is also called Adhi Chidambaram. The Chidambara Rahasya is also here. Vishnu has a place near the Nataraja here as in Chidambaram. Indira, Iravadha (the white elephant) Vishnu, Sun, Moon, Agni (fire) worshipped the Lord. It is in Thiruvengadu Pattinathar had Sivadiksha, ascesticism.
Separate Sannidhi for Mercury:
Of the nine planets, Mercury is the lord to bless with good education, knowledge, eloquence, music, astrology, mathematics, sculpture, medicine, scholarship in languages. A temple for Chandra (moon) the father of Mercury is just opposite to the Mercury with Chandra Pushkarani theertha. If mercury is not favourably placed in a horoscope, the native may not have children. Also he/she will have nervous debility and lack of knowledge. They have to propitiate Lord Mercury. Musicologists and film makers worship Mercury.
Pillai Idukki Amman:
When Thirugnanasambandar reached the borders of Thiruvengadu, the whole place looked like Sivaloka and the sands Sivalingas. He hesitated to place his legs on this holy land and cried Amma (Oh! Mother). On hearing his voice, Goddess Periyanayaki appeared there and took the child on her hips. The idol of Periyanayaki with Thirugnanasambandar is majestically installed in the temple.
6.00 a.m. to 12.00 a.m. and 5.30 to 9.30 p.m. are the Puja timings. Thiruvengadu is in Nagapattinam district. It is 10 Kms southeast of Sirkali on the Poompuhar road. Buses are available from Sirkali. Nearest Railway station is Sirkali and the airports Trichy and Chennai.
Every month is a festival month. There will be flag hoisting on Tamil Masi Month (February-March) on the Punarvasu star day and continues for 10 days.
The demon Maruthuvan, with the boons gained from Brahma misused it torturing the Devas. The Devas went to Shiva for freedom from the demon. The Lord advised the Devas to go to Thiruvengadu and live there in disguise. Shiva sent his vehicle Nandhi and defeated the demon. The demon, without losing heart, performed penance, got the trident (Soolayudham) and injured the Nandhi, which is still visible on the idol. Infuriated by the injury on the Nandhi, Lord Shiva converted his anger into the Agoramurthy form. On seeing the Lord, the demon surrendered at his feet and begged his pardon. He also prayed that those worshipping Agoramurthy would not have enemies at all.
