The temple priests perform the pooja (rituals) during festivals and on a daily basis based on Vaiksana Agama. As at other Vishnu temples of Tamil Nadu, the priests belong to the Vaishnavite community, a Brahmin sub-caste. The temple rituals are performed six times a day: Ushathkalam at 7 a.m., Kalasanthi at 8:00 a.m., Uchikalam at 12:00 p.m., Sayarakshai at 6:00 p.m., Irandamkalam at 7:00 p.m. and Ardha Jamam at 10:00 p.m. Each ritual has three steps: alangaram (decoration), nivedhanam (food offering) and deepa aradanai (waving of lamps) for both Vanamamalai Perumal and Thayar. During the last step of worship, nagaswaram (pipe instrument) and tavil (percussion instrument) are played, religious instructions in the Vedas (sacred text) are recited by priests, and worshippers prostrate themselves in front of the temple mast. There are weekly, monthly and fortnightly rituals performed in the temple. The major festival, the twelve-day Brahmotsavam, is celebrated during the Tamil month of Thai (January - February).
Vishnu is considered as alankara priyar (one who prefers decoration), and Shiva as abhisheka priyar (one who prefers ablution). Vanamamalai temple is one of the few Vishnu temples where ablution is done for the presiding deity on a daily basis. At around 7 am every day, ablution is performed on the presiding deity with milk, curd and other pooja items. The ghee used for ablution is poured in the oil well in the temple, which is considered sacred.During the festival occasions, the festival idols are brought to the Vanamamalai Mutt located outside the premises of the temple.
Sthalapuranam :
This sthalam is also named as Naanguneri, Seeravaramangai and Vanamamalai. Since there are 4 big Lakes in this sthalam, this sthalam is named as “Naangu Neri”. (Naangu means four). But at present only one is found. This sthalam is one of the Ashta (eight) swayambhu (Which grows (or)develops on its own) sthalams. Other seven sthalams are Badri Narayanam, Mukthi Narayanam, Naimisaranyam, Pushkaram, Tiruvenkadam, SriMushnam and Thiru Varaagam.
It is said that the Moolasthanam was immersed in the lake water. Even if the lake is flooded with water, there will be around 2 feet high of water around the Garbhagriha (Moolasthanam).
Inside this sthalam is an oil well of 25 feet height and 15 feet width. The well doesn't have water but has a rich oil, which extracts oil instead of water. The oil which is found in the well is said to have medicinal values and said that it cures many diseases. Daily, the Emperumaan of this sthalam is done the thirumanjanam using 6 padis (1 padi= around 1 1/2 Kgs) of Gingelly oil and Sandalwood oil. After the thirumanjanam is over, the oils are poured into the well itself .
If any devotee needs some amount of oil from the well, they must give the same amount of gingelly oil to the devasthanam and it is poured into the well and given the medicinal oil.
To get the Aathma Gnanam, Aathma Arul (blessing) and Aathma Bhakthi, the permanent soul (or) Aathma which resides on the temporary body should be clean and purified. Having this as cleared only, we get to achieve all other things. Our body, speech and activity should be clean. Old age is the caution for death and it is the final action for the free of our soul. Till the soul is in our body, it should be without any harm and diseases and should be clean. To explain this, the Emperumaan of this sthalam gives his seva and also gives the oil which cures many diseases.
So bhaktaas who worship this sthalam can get the dharshan of the Emperumaan and also the curable oil.
This sthala perumal gave his pratyaksham to Indiran, Romasa Maharishi, Brighu Muni and Maarkandeya Maharishi. He gave his sev to these four great aathmas as “Aadhi Maruthuvan” (Maruthuvan means doctor). The persons who has the diseases are given the treatment by facing him towards East – west direction. As the same way, the perumal Thothatri Naathan gives his seva facing his thirumugam towards the east direction.
It is said that a king who belonged to the Sindhu empire got the sabham from Romasa Maharishi to become like a dog. After becoming the dog, the king came to this sthalam and took a bath in the sthala pushkarani to get out of the Sabham.
On the entrance of the Temple is the Pandhal Mandapam and along the side, we can find very big mandapams where Golden Chariot and Golden Chapparam (another kind of perumal’s Vaaganam) are kept. These are taken out during the utsavam done in Panguni Uthiram. On the north side, we can find the Vaanamamalai Jeeyar Madam.
When entering into the main temple, we can find Sevvanthi Mandapam which is built by Sevvanthi Naayakar. In this mandapam only, the utsavar gives his seva during utsava times. On the left side of this mandapam, we can find Veerappa Naayakkar mandapam, in which all the pillars are beautifully sculptured with numerous shapes. When passing through this mandapam, sannadhis for Lakshmi Narayanan, Lakshmi Varagar, Venugopalan and Dasavatharam are found.
After crossing the Kodi maram, we can find Kulasekaran mandapam. Here vadakku Naachiyaar, Therku Naachiyaar, Manavala Maamunigal, Udayavar, pillai ulaga Asiriyar and except Nammalwar, all the Alwars are found in separate sannadhis. Nammalwar is found as “Sadagopar” in “Sadaari” (this is kept on our head in Vishnu temples) as “Sadagopar Sadaari” in utsavar sannadhi. Also, separate sannadhis for Sri Ramar, Sri Kannan, Chakaratalwar are found.
After crossing all these, we can reach towards the main moolavar sannadhi and can find Thothadri nadhan in Veetrirundha thirukkolam and opposite to him Garudalwar is found.
Moolavar is found along with two pirattiyaars in veetrirundha kolam and Rambhai, Thilothamai who are called the “Deva loga women” serve the perumal, Brighu Maharishi, Maarkandeya Maharishi, Chandra – Soorya, Vishwakshenar are found. The Aadhiseshan, serves as the Umbrella for Thothatri Nathan, he is giving his seva to the bhaktaas.
Utsavar Deiva Nayagan is found along with this pirattiyaars, Srivara Mangai thaayar and Andal by having Maga Kandigai (which is said to be the most precious and valuble ornament of the perumal) in very big peetam is found.
This sthalam is also called as “Vaanama malai” because a pandiya king married a Cheran daughter and he got the name as “Vaanavan”. Since he built this temple, this sthalam is called “Vaanama malai”. It is one of the said story about this sthalam.
