The moolavar is Balasubramanian . There are separate sanidhis in one line for Vinayakar, vishwanatha and Kamakshi this in turn leads to the main sanctum sanctorum.
Outside there is a separate sannidhi for vinayakar and a Kalyana mandapam where a 6 faced utsava murthy is placed, there is a sanctum for bhairavar and navagrahas. All except the Moolavar are carved out of green granite.
Legend ties this temple to the story from Uthara Ramayana when Sri Rama performed the Aswamedha yagna and Lava-Kusa captured his itinerant horse. A battle ensued and Lakshmana was defeated by the young boys while still being unaware of each other's identity. As the place that brought glory to the young boys, the town became famous as "Siruvapuri". The town is also knows as "Siruvembedu".
This temple has an idol of a peacock made out of Emerald (Maragadha Mayil) and also a Maragadha Vinayaka. In many ways this temple is closely tied to that in Tiruvannamalai. The Sthala vriksham here is Magizha maram which is also that in Tiruvannamalai. Vallimalai swamigal was sent here by his Guru Seshadri Swamigal of Tiruvannamalai to spread the Tiruppugazh. When Arunagirinathar travelled here and sang Murugan's praise, he had a vision of the Lord appearing on a Mayil similar to his manifestation out of a pillar in Tiruvannamalai.
This temple houses an Utsava murthy of Lord Muruga wedding Valli weighing 120 kgs. This temple is also curiously linked with 2 National holidays, Independence and Republic days. While Aug 15th is also commemorated as Arunagirinathar day since he was born towards the end of the month of Adi in many Murugan temples and is celebrated with the all day singing of Tiruppugazh, peripatetic pilgirms flock to this temple at Siruvapuri from surrounding areas on Jan 26th.
The striking feature outside was the fresh vegetable market going fully strong on a Sunday morning
The temple is well managed and there was a strict ban on mobiles and Camera inside.
