Tiruvonam starrers are devout and respect elders.  They participate in public affairs with interest.  They are helpful in nature and own lands. The temple was built by Krishnadevaraya.  There are shrines for Sri Andal, Navaneethakrishnan with Bama and Rukmini, Bhakta Anjaneya, 9 Nagadevadas, and Ashtanaga Garuda the eagle vehicle of Lord Vishnu.  The sacred spring Pundarika theertham is just opposite the temple.  The temple is under the administration of Hindu Religious &Charitable Endowment Board.

Besides Tiruvonam starrers worshipping in the temple for relief from doshas they face, others include ENT surgeons, lawyers, audio businessmen and students aspiring excellence in their academic pursuits.  Those facing problems in marriage affairs often seek the blessings of the Lord.

Of the 27 stars, only 2 have the prefix Tiru, Tiru Onam attributed to Perumal and Tiru Adhirai to Lord Shiva.  Tiru represents all auspiciousness.  The beauty and luster of Chandra the Moon began to diminish due to a curse.  One of his wives, the deity of Tiruvonam star performed intense penance on Perumal for his remedy.  Pleased with her penance, Perumal appeared before her on a Tiruvonam star day and relieved Moon of his curse.  Since then, this shrine assumed importance for the Tiruvonam star.

Thos born of Tiruvonam star are advised to visit and worship in this temple on the star days, Rohini and Hastham star days and on the third day from the New Moon day called Moondram Pirai in Tamil and perform abishek and archanas to Perumal to gain wisdom.  As this star is specifically related to Perumal all pray here. The standing form of Lord Perumal on the Avudayr of Shivalinga symbolizes the oneness of Shiva-Vishnu worship.  Hence, Pradosham related to Shiva also is devoutly observed in this temple.

Of the 108 Divya Desas – holy places connected with Vishnu worship, Tiruparkadal cannot be reached with human body as it is not on earth.  To make up this loss to the devotees, the worship in this temple gives the devotee the gift of Tiruparkadal darshan, the 107^th Vishnu Divyadesa.  There is no Sorgavasal system in the temple.  Instead, there are three entrances through which Perumal can be worshipped directly at the sanctum itself on the Vaikunda Ekadasi day.  This is a rare structure in the temple.

Maharshi Pundarika took up a pilgrimage to Vishnu temples.  When he landed on this temple at Narayana Chaturvedhi Mangalam, he was shocked to see Shiva in the sanctum and retreated regretting the mistake.  An aged person intercepted him and told the Rishi that what he saw was the shrine of Lord Vishnu.  Rishi denied.  The aged person took the Rishi to the sanctum and stood on the Avudayar as Prasanna Venkatesa Perumal and explained him that Shiva-Vishnu were one and not different from each other.  The Lord also told the Rishi that as he could not worship Vishnu in Tiruparkadal, the darshan was offered to him here.  As the Lord offered his ‘Prasanna’ – darshan, the Lord is praised as Prasanna Venkatesa Perumal.
