The Lord of the temple is praised by Saint Tirunavukkarasar in his Thevaram hymns. This is the 20th Shiva temple on the southern bank of Cauvery praised in hymns.

Mother Tirupurasundari blesses the devotees from a separate shrine. There is a shrine for Lord Nataraja with 8 hands in a dancing posture with Lord Kasi Viswanatha, Sage Agasthya, Lord Gananatha and three Saivite Saints Tirugnanasambandar, Tirunavukkarasar and Sundarar.

According to scriptures, the devotee will derive equal benefits by having a bath in the tank of this temple as having one in the Mahamagam tank in Kumbakonam. Kundhidevi mother of Pandavas incurred dosha as she had children with Panchaboodhas. She approached Maharshi Naradha for a solution. Naradha suggested that she should bathe in seven oceans for relief. When Kundhi Devi pleaded her inability to do so as women, Narada suggested that she should worship Lord Kalyana Sundareswarar and he would offer the next suggestion then. Before Kundhi finished her prayers here, Narada brought the waters of the seven oceans (Saptha Sagaram) to the tank in the temple. Kundhi belonging to Magam Star bathed in the tank and was relieved of her dosha. Thus the Nallur temple tank derived equal importance as that of the Kumbakonam Mahamagam tank offering high benefits to the devotees, according to scriptures.

Lord Kalayana Sundareswarar appears in five different colours each day copper, pink, golden, emerald green and one that could not be named or recognized. Hence, is praised as Panchavarneswarar God of five colours. 
Lord granted His Feet Darshan (Pada darshan) to Saint Tirunavukkarasar.  Hence, the tradition of Sadari blessing as in Vaishnavite temple came into practice here too. Mother Ashtabuja Makali Mother with eight hands blesses the devotees in the temple. Somaskanda Murthy of the temple is a replica of the one in Tiruvarur temple. During Masi Magam day in (February-March), He comes in procession in the prakara. During the procession, though devotees fan Him for the heat, we may observe pearls of sweat on the idol.

It is said that the Vilwa tree of the temple is the first one on earth, hence called Aadhi Tree. It would be a unique luck of those praying the Lord with the leaves of this tree.

Lord Gana Natha blesses here in the form of a Balipeeta at the entrance of West Tower. It is only in this temple and in Kasi now Varanasi, Gana Natha graces in this form. A special puja is celebrated annually for Gana Natha.  People of this place and those around offer the one time milk they get from their cows for abishek. But devotees cannot see this puja. Amarneedhi Nayanar one among the celebrated 63 Nayanmars was granted salvation by Lord in this temple.

During the divine Shiva Parvathi wedding in Mount Kailash, the place went down due to the heavy weight of the presence of all the beings to have this darshan. To balance the level of the earth, Lord Shiva sent Sage Agasthya to South. The sage had to sacrifice his wish of witnessing the wedding. Lord assured him that He would grant the wedding darshan to him in this holy place. Enjoying the divine darshan here, Sage Agasthya installed a Linga right of the Sundaralingam for his worship. That Linga is behind the presiding Lingas

This sivasthalam temple is located to the east of Uthamadhanapuram, which is 2 Kms from Papanasam railway station. This sivasthalam is 25 Kms from Thanjavur and 15 Kms from Kumbakonam.

This Shivastalam is a Maadakkovil built at an elevation and this hillock is referred to as Sundaragiri. It is located at a distance of 6 km from Kumbhakonam. The Shivalingam here is believed to manifest itself in five different colors in a day (hence Panchavarneswarar). Aavoor Pasupateeswaram is considered to be the 20th in the series of Tevara Stalams in the Chola kingdom located south of the river Kaveri.

Agasthyar is said to have been blessed with a vision of the marriage of Shiva here. Bhringi Muni and Narasimhar are said to have worshipped here. Tirunallur is also referred to as Dakshina Kailasam, and it is related to the legend of the trial of strength between Vayu and Adisesha where a peak of Mount. Meru (Sundaragiri) fell at Nallur and formed a Shivalingam. Legend also has it that Kunti the mother of the Pandavas bathed at the Saptasagara theertham, there is an image of Kunti in the temple. It is also believed that Mucukunda Chola associated with Tiruvarur, placed the image of Tiruvarur Tyagaraja at this shrine (enroute to Tiruvarur) for a three day period and offered worship here.

An image of Kalyanasundareswarar and his consort are seen in the sanctum behind the Shivalingam. Two worship services are offered here each day. During the annual festival, festival images of deities from nearby towns converge to participate. The practice of placing an icon containing the imprint of the deitys feet on the heads of devotees is carried out here like in Vaishnavite temples, commemorating Appars surrender at the deitys feet here at Tirunallur. The image of Natarajar here is of great beauty. Inscriptions from the period of Rajaraja I and from the period of Uttama Chola are seen here, in addition to several from later years.
