Sacred Significance
The temple holds immense mythological importance. It is traditionally believed that this is the divine where Lord Shiva revealed the profound secrets of the Vedas to Goddess Parvati. The very name “Uthirakosamangai” reflects this legend:
-
“Uthira” – sacred teachings or upadesha
-
“Kosa” – hidden knowledge or scriptures
-
“Mangai” – Goddess Parvati
Thus, the temple symbolizes the transmission of divine wisdom from Shiva to Parvati, marking it as a spiritual epicenter of knowledge and enlightenment.
Main Deities
The presiding deity is Lord Shiva, worshipped here as Mangalanathar, along with his consort Goddess Parvati, known as Mangalambigai. Devotees believe that worshipping here brings auspiciousness, spiritual clarity, and divine blessings.
Unique Highlight – Maragatha Natarajar
One of the most extraordinary features of the temple is its rare and priceless idol of Lord Nataraja. This idol:
Stands approximately 6 feet tall
Is carved entirely from a single piece of emerald (maragatham)

Due to its delicate nature, the idol is usually covered with sandal paste throughout the year and is revealed to devotees only during special occasions, making its a rare and sacred experience.
Historical and Cultural Importance
Beyond mythology, the temple is a significant monument of ancient Tamil civilization and Shaivite tradition. Its architecture, inscriptions, and rituals reflect centuries of continuous worship and devotion. The temple is also associated with early forms of Nataraja worship, further enhancing its spiritual stature.
