The Moolavar is Naavaai Mukundan, Narayanan seen in standing posture facing east. On the other bank of the Bharathapuzai river, there are temples for Siva and Brahma. Devotees perform the annual rites for their ancestors at this sthalam. Nine yogis once performed yagam here and hence the place came to be called Thirunavayogi (nava-nine), which later became Thirunaavaai. This is one of the few temples in Kerala with separate sanadhi for Lakshmi.
Mahalakshmi and an elephant were both worhsipping the Lord with the lotus flowers from a tank. At one time, the elephant could not find any flowers & he prayed to the Lord to show him a way. Lord Vishnu asked Lakshmi to be seated by his sie & the elephant now had enough flowers & happily worshipped the Lord along with Lakshmi.
