There are idols of Lord Vinayaka, Nagaraja, Veerabadrar, Perumal wearing corpse garland, Nallamadasami, in the temple.  The temple is under the management of Senaithalaivar community.

Devotees pray for removal of obstacles in wedding matters.

Mayilerum Perumal Sastha in the sanctum sanctorum graces as Lord Muruga with vahans as peacock, elephant, horse and dogs.  As Lord Muruga appears as Sastha, Sudalai (probably a guardian deity) also is in the temple.  The reason behind Sastha-Murugan form is not clearly known.

There are some verses devotionally chanted by the devotees;

Oh! Mayilerum Perumal, please protect your subjects

You are in sweet environment with nightingale singing

On the palm trees in Varadarajapuram village irrigated

By Srivaikundam canals, you are on the north

Bless us with a determined mind on you.

You are among the dancing ferrtile fields

Nalangudi Perumal, we prostrate at your feet.

Those facing obstacles in marriage proposals perform pujas to Swami and Padala Kanni Amman and distribute fruits to visiting devotees.  They also carry milk pots, do tonsuring and ear boring in the temple.  People believe that Mayilerum Perumal is their constant custodian helping in fulfilling their wishes.   Water is fetched from the canal of Tambirabarani river for abishek to Padala Kanni Amman on Panguni Uthiram festival day.

Kanni Amman was the only sister of seven brothers then living in Nalangudi in Srivaikundam.  It was under the British rule.  A white officer wanted to marry Kanniamman who was very beautiful.  The brothers, naturally did not accept to the proposal and also understood the consequences of their refusal to the proposal.  To avoid political action, the brothers dug a deep pit near the Nalangudi Sastha Temple, and buried their sister alive and built a temple in the name of Padala Kanni Aamman, began conducting pujas which is being continued even today.
