The temple has 16 Towers, 18 Vimanas, 7 prakaras, 7 mandaps and 9 sacred springs-therthas.  In the 11 tier Rajagopuram there are no sculptures up to six stages from the base.  All God sculptures are from the 7^th stage only.  This is a rare and different type of Rajagopuram in Mannargudi.

For the beauty of temple cars-Raths-‘Ther Azhagu- in Tamil’ Tiruvarur stands as outstanding example.  For the beauty of temple Compound Wall-‘Mathil Azhagu-in Tamil’ Mannargudi is numero uno.  Theertham Tank is a little far from the temple.  This is the place where sages performed penance for the darshan of Lord.  This theertha is considered as Jamuna River-Yamuna- and is praised as Haridra Nadhi.  The float festival is celebrated here on Aani Poornima day in June-July.

It is the staunch faith of the devotees that prayers to Lord Rajagopalar-Vaasudeva would bless them with prosperity in life, happy wedding, removal of adverse aspects on children, health of cattle and all happiness.

 When cruel Kamsa put his own sister Devaki and her husband Vasudeva in prison, Lord Vishnu appeared before them and assured that He would be born to them.  This is His first Leela-divine play Krishna Leela.  He appeared as Vaasudeva to Gopilar and Gopiralayar then.  His life in Gokhulam as a shepherd was the 32^nd Leela.  Based on these events, the presiding deity is Vaasudeva and procession deity as Rajagopala.  While opening the Vaasudeva shrine in the morning, Gopuja-cow puja and Gaja puja-puja to elephant are performed.  Procession deity is also called Rajamannar, hence the name of the place Mannargudi.

Rajagopala Swami appears as a shepherd in simple attire using it also as a turban and wearing all the child ornaments.  There are also a cow and two calves with Him.  Kamsa engaged a wild elephant named Kuvalaya Peetam to kill Balarama.  Lord Krishna killed that elephant.  Remembering the event, Lord is holding a tusk in His left hand.

Lord Krishna arranged a competition among the Gopikas bathing in Yamuna River.  The contest was that they should dress properly and wear the jewels after the bath.  One Gopika could not find one of her ear ring.  They found it at last in the ear of Krishna and were excited with joy to see its beauty in His ears.  Based on this event, Lord in the temple has a Thadanga-ear ring in one ear and Kundalam-ring  in the other.

Milk is the main nivedhana for Lord.  This is given as Prasad also.  As in Madurai Kallazhagar temple, Dosa is the nivedhana here only in evening pujas.

18 day Brahmmotsavam is celebrated in the month of Panguni-March-April.  18 has a significance in Lord Krishna’s Avtar life.  Duration of Kurukshtra war was 18 days.  Srimad Bhagwat Gita has 18 chapters in the immortal Mahabharata epic.  This is a famous festival in the temple.  Lord appears in 32 types of Aalankaras representing His 32 Leelas.  The Butter Pot festival is celebrated on the 16^th day when Lord comes in procession as crawling baby with butter in hand.  That is also offered as nivedhana.  After the Alankara, when Lord comes to a mandap in the place, people throw butter balls.  He returns to the temple in Horse vahan in the evening.

During this festival, Lord also appears as Sri Andal, on two faced bird named Kanda Peranda Pakshi and as Sri Rama dressed in stark on the Pancha Mukha Anjaneya vahan.

Mother Sengamala Thayar blesses the devotees from a separate shrine.  Special Tirumanjanam is performed to Her on Poosa Star day-Mother’s birth star.  On the fourth day of Thai month-January- Lord and Mother appears together on a single throne.  Garuda is in female form before Mother’s shrine.  Those facing problems in marriage and concerned with the welfare of children, light ghee lamps to Garuda.  Though this is a Perumal Temple, Maya, born before Krishna is blessing here as Durga in the Vaasudeva Perumal ghoshta.  Special pujas are performed here at Rahukalam time.  Devotees tie cradles here seeking child boon.
