Theerthakulam is on the left side of the eastern entrance.  Lord Agastheeswara facing east with one Kalasa and Chelli Amman with one Kalasa in a separate shrine facing south grace the devotees.

Those physically and mentally weary, incurring the wrath of Mothers pray to Lord  for recovery of health.

This is one of the temples built by Cholas.  The temple enjoys added reputation as Santhana Ramar, Yamunambal and Alangudi Guru Bhagwan temples are also close by.

Those who know the secret of the five energies – earth, water, fire, air and space – and their merger into one another and their functions are praised as sages.  During the wedding of Lord Shiva and Parvathi, every one from the three worlds assembled at Kailash mount and due to the heavy weight, north began to sink and the south began to rise.  Lord Shiva, to balance the level of the earth, asked sage Agasthya to go south to set right the imbalance.  The sage sought time to see Lord’s marriage function and then proceed, Lord Shiva said that any delay in his departure to south would cause the north to sink in sea, the sage obeyed and left the marriage venue forthwith.  Lord promised Agasthya that He would grant him the wedding darshan later.  The sage journeyed non-stop worshipping the Lord.  This place also was on his route.  As the sage worshipped Lord here, He is praised as Agastheeswarar.

This is one of the 108 temples built by Cholas.  Due to lack of maintenance, the temple was covered with wild bushes.  Renovations were carried out then installing new idols with the permission of HR & CE.  The consecration took place on February 9, 2014.
