There is an interesting legend about the lord of this temple.  Once upon a  visit to this place  saint Thirumangai Azhwar, one of the 12 Vaishnava Tamil saints, found the temple doors  locked. Grief-stricken and disappointed as he was, he sang in praise of Parimala Ranganathar, hoping the door would be opened soon for him,  but the door remained locked. His  continuous singing of divine hymns  did not reach the lord's ears. Having lost his patience  the terribly upset Thirumangai Azhwar told the deity Parimala Ranganathar to keep the temple for himself. No sooner had he uttered these words, than, to his surprise, the doors had flung open for the pious saint by the lord.
At this temple, daily worship is held  with accompanying music with nagaswaram (wind instrument) and tavil (percussion instrument), chanting of  sacred mantras by  temple priests. After the puja, the devotees pray to god and many  prostrate  before the deity - symbolic of total surrender to the Almighty. There are weekly, fortnightly and monthly  temple and puja rituals. 

The food offerings during the six times are curd rice, spiced rice, dosa, venpongal and sugar pongal respectively. In many temples, this ritual is not being followed. It is one among a few temples where naiyadvam (food meant for the lord) is prepared in the temple kitchen (madapalli) six times a day. 

The well-known- festivals of this temple  are the Chitrai festival, the 10-day Aaandal Aadi festival (July–August), Vaikunta Ekadasi (Margazhi; (December - January), Makara Sank(ranthi (January and Panguni Brahmotsavam ( Panguni ;March - April).
