There are shrines for Ganapathy, Vishnu, Sastha and Nagar in the corridor (prakara) of the temple.

As the Nandhi in the temple had been installed by Lord Shiva Himself, it is said that this is choice temple for worship on Pradosha days (the 13th day either from New Moon or full moon days). This is an ideal temple for those seeking to mend their wicked mind with sins of serious crimes as murder committed knowingly or unknowingly.

Generally, devotees go round the Prakaras thrice in the temples. But it is said that even a single round blesses the devotee in this temple with the huge benefit of doing so throughout the year. A good reason is attributed to this graceful benefit. There are 12 Shiva temples in this region. These are called Shiva running temples – Shivalaya Otta koilgal. On the Mahashivarathri day, devotees run from one Shiva temple to the other. The distance between the temples is 100 km. Even today, this practice is followed by the people in Tirunandhikarai.

The place where the bull (Nandhi) is installed is named Vrushaba Mandapam where the stamp of the foot of the animal and the rope used by the Lord are still visible. The whole reputation of the temple is in its Star hall or Nakshatra Mandap. Going round once in the temple brings the devotee of a one year benefit. Sage Parasurama sought relief from the sin of killing his own mother by worshipping Lord Nadeeswara.

A bull in the region was threatening the residents. All prayed to Lord Shiva to contain its violence and the Lord obliged. While pulling, the bull fell in a pit and could not come out. It became the Nandhi of the temple. The installation is designed as if it is in the pit. As the Lord Himself installed it, the place is called Tirunandeeswaram. The symbols of the bull foot and the rope are still visible in the temple.
