Lord Makara Nedunkuzhai Kadhar Perumal blesses the devotees from the sanctum sanctorum under the Badra Vimana-tower above the sanctum.

Devotees pray here for relief from the adverse aspects of planets faced by them.

Nine Sri Vishnava Kshtras in this region is linked with Navagraha importance.  Lord Perumal Himself represents the planets in these temples as shown below:

1.  Sun                                                     :  Srivaikuntam

2.  Moon                                                  :  Varagunamangai (Natham)

3.  Mars – Sevvai                                    :  Tirukolur

4.  Mercury-Budha                                 :  Tirupuliankudi

5.  Jupiter – Guru                                   :  Azhwar Tirunagari

6.  Venus – Shukra                                  :  Thentiruperai

7.  Saturn – Sani Bhagwan                     :  Perunkulam

8. Serpent planet – Rahu                        :  Twin Thirupathi  }
9. Serpent Planet – Ketu                         :  Twin Thirupathi  } Tholaivilli Mangalam

The temple is big in size.  Mother Earth – Bhoodevi chanted the Ashtakshara Mantra taught to her by Sage Durvasa, performed penance on Lord Perumal.  When she came out from the sacred river Tambiraparani after a bath, She got two precious ear rings and came to be known as SriPerai – Thiruperai in Tamil.  She offered the two fish shaped ear rings to Perumal on a Panguni Poornima day in March-April, thus Perumal became Nedunguzhai Kadhan.  Since Mother Bhoomadevi was named Sri Perai, the place also was named Thenthiruperai.  Varuna the God of Rains performed penance on Perumal here to cleanse himself of his disrespectful behaviour against Jupiter-Guru, performed Tirumanjanam to Lord and the place received rains then, according to Sthala Puranas.
