Lord Narasimha appears with His conch and discus in the sanctum sanctorum under Chandravimanam.  The philosophy is that Chandra, brother of Sri Mahalakshmi is taking care of the Lord.  In the sanctum sanctorum both Lord and Mother are in a standing form.  There is Sri Chakra in the seat (peetam) of Lord Narasimha.  There is a salagrama in the Arthamandapa which was originally worshipped as SriNarasimha, called Aadhimurthy.  Special pujas are performed to the Lord on New Moon, Full moon, Ekadasi (11^th day either from New Moon or Full moon day) days and on Tiruvonam star days.  The Eagle vehicle of Lord Garuda is opposite in a worshipping form.  Lime and Tulsi are offered as Prasad, which devotees keep in their house for the welfare of the family.

Devotees pray to the Lord here for family prosperity, release from debt burdens, develop calm qualities.

Sarpa Vinayaka: In almost all Vaishnava temples, Lord Vishnu is found sitting on Adisesha the serpent bed.  In temples where the Lord is in a standing form, Adisesha serves Him as an umbrella. In this temple, there is a shrine for Vinayaka in the Prakara with Adisesha serving him as an umbrella.  Hence, He is called Sarpa Vinayaka.  As this a Vishnu temple, Lord Vinayaka is seen with Adisesha.  Those facing adverse effects of planets Rahu, Ketu and Mars and those worried on the welfare of children pray to Lord Vinayaka in this temple.  Devotees perform Tirumanjanam with turmeric.

The temple is on the bank of a canal.  Thalam means a canal and Karai-bank, hence the place is known as Thalakarai.

The object of Narasimha incarnation of Lord Vishnu was to destroy the Demon Hiranya.  The demon had such a boon that he could not be killed by any power, any time, any weapon etc.  Using the loopholes in his boon, Lord Vishnu took the Narasimha form (human body with a lion’s face) and destroyed him.  The Lord was too furious then that nobody could go near Him.  Mother Mahalakshmi sat on his lap and the Lord became calm and graceful.  Based on this truth, in all Narasimha temples, Sri Mahalakshmi is seen sitting on the lap of the Lord.  In this temple, Sri Mahalakshmi is in a separate shrine while Lord Narasimha is in another shrine.  This is a very rare form in a Narasimha temple.
