There are shrines for Nardana Ganapathi, Uthishta Ganapathi, Appar, Sundarar and Tirugnanasambandar.

Excellence in education, removal of obstacles in marriage talks and child boon are the prayers submitted by devotees to the Lord.

In the place of Lingoghbava, Lord Arthanareeswara graces the devotees from the sanctum sanctorum.  Lingodhbava is the form of Lord Shiva whose feet and head was sought by Lord Brahmma and Lord Vishnu. The Parasunathalingam belongs to the Beejakshara Linga group, meaning a round base with eight corners facing west.  This is one of the sacred Shiva Shrines praised in Thevaram hymns.

The hymns sung by Sambandar, Appar and Sundarar belong to the Vaiputhalam classification.  Vaiputhalam hymns will have mention of two sacred places in one song.  The other significance in the temple is that Lord Muruga is holding the trident in between the two fingers in the left hand, attributed to Shakti instead of His Vel weapon.

Muzhayur: Muzhavu is a drum instrument used for making announcements of royal and official orders also used in temples for festival and Puja announcements.  There were people who were skilled in using this instrument for singing Veda hymns.  It is said that the Boodhaganas – army of Lord Shiva – use to sing Vedas on Earth with this instrument on Akshaya Thrithiya day. The Boodhaganas jump to height of 10,000 yards high while playing this instrument.

Thrithiya worship: Special pujas are performed during the Thrithiya days (3^rd day from New Moon or Full Moon days).  Besides the special Akshaya Thrithiya day falling in April-May, this puja is followed during all Thrithiya days with ghee rice offered to Lord Shiva.  It is said that this puja is performed as a treatment to indigestion, diabetics, blood pressure etc.

Devotees also make garlands made of the pearls of Pomogranate Fruit (Madhulai) and offer it to the lord for development of fallow lands, idle money and other still properties. On the day, Panchamurthis – fives Gods - Lords Vinayaka, Parasunathar, Gnanmbikai, Subramaniar, and Chandikeswara are taken procession.  Special pujas are performed in the temple for those who had lost their money for standing surety for others.  Devotees offer jasmine garlands made by themselves to the Lord.  They don’t buy these garlands.

Sage Parasurama came to Muzhayur for release from the Brahmmahati dosha that afflicted him for killing his own mother as instructed by his father Jamadagni.  He installed a Shivalinga here, worshipped and was released of the evil aspect.  Hence, the Lord is named Parasunathar.

The temple presided by Lord Parasunathar with His Consort Gnanambika was in a bad condition.  Due to the painstaking efforts of the local people, the Rajagopuram is under renovation.  Also cleaning the temple (Uzhavarapani – weeding out the thorny bushes on the ground – a great service undertaken by sage Tirunavukkarasar) is also on.

Once the Akshaya Thrithiya festival was conducted in a grand manners as the Kumbakonam  Mahamaham festival.  Many from the north also thronged here then.  During this festival the Lord would be garlanded with gold coins.  This reputation dimmed later.  Efforts are on to rebuild the reputation again.
