Sirkazhi, known for the famous temple for Lord Shiva known as Brahampureesar, is also associated with the birth of Tirugnanasambandar, one of the 3 most revered Nayanmars of that time. When Sambandar as a 3 years old child was crying on the banks of the temple tank, Goddess Parvati appeared in person and fed him with Gnanapaal, (wisdom of milk). Thereafter, Sambandar started singing in praise of the God Shiva with his first and famous Pathigam "Thodudaya Sevian".

Accoding to mythology, when the great deluge (pralayam) started submerging the whole earth, God Shiva carried the 64 arts in a Thoni (boat) with him and landed at Sirkazhi which was not submerged in the great deluge. God Brahma after worshipping Shiva here, started afresh his job of creating life forms. Becuase Brahma worshipped Shiva, he is known here as Brahmapureesar and also as Thoniappar for carrying the 64 arts with him in the Thoni (boat).

About the temple: The Shiva temple at Sirkazhi is a big complex and there are 3 separate shrines for God Shiva here - Brahmapureesar, Thoniappar and Sattnathar.
