Lord Siva is the main deity of the temple. Lord Siva in the form of �Linga� is to signify the philosophy of God being both with form and formless. As one of the Hindu trinity, Lord Siva occupies a pride of place in Hindu temples and a special place in Tamil Hindu devotees. Though he is portrayed as �Linga� in the main alter he has taken many forms to enable the devotees to cherish and adore. As Dakshinamurthy, Lord Siva appears as teacher to seven Rishis (Saints). As Arthanareeswarar he appears as Parvathi amman and Lord Siva in one body, depicting the complementary nature of the genders in life. He also appears as Nadarajah, the Lord of cosmic dance. This is to make devotees realize by his perpetual dace the world undergoes; the cycle of Evolution (Creation), Revolution (Sustenance) and Resolution (Re-absorption) is done by hiom. The �Vigraha� of Linga installed at the temple is not manmade statue. It was picked up in the holy waters of the Ganges near Kasi ( Banares) and was kept in puja before installation. The Sivalingam in the main sanctuum is formed by spontaneous growth of its own and therefore called “Vidankeeswarar”, the largest ever seen in North America. The moorthi installed here is named as �Vaidyanatha Swamy�.
The consort of Lord Siva is installed in a beautiful alter on the left side of Lord Siva. The �vigraha� itself is cute granite one with divine grace and beauty personified. She is called �Thaiyal Nayaki� . There are special festivals (Adipooram) celebrated at this alter and the main festival will be the Navarathiri in Sept � Oct. of every year.

Lord Murugan is the second son of Lord Siva and is considered as the commander- in � chief of the divine army. He is the main deity worshipped by the Tamils around the world.

Special puja to Sani is very popular in the month of Puraaasi (Sept-Oct), and also to Sevvai in Aadi month. Specific �Santhi Homa� or special pujas are conducted at the temple to reduce or remove the difficulties in life by the influence of one or the other of Navagraha.
