agastheeswarar temple, villivakkam, pic 7--10

During the Wedding of Lord Shiva with Mother Parvathi in Mount Kailas, Sage Agasthya was in south performing Shiva Puja in this place.  Two demon brothers Vilvalan and Vatapi caused hindrance to his puja.  Agasthya killed them with his penance power and incurred the Brahmmahati dosha-a sin caused by killing others, good or bad.  He worshipped Lord Shiva here for relief from the dosha and also relief from any disturbance to perform his pujas.  Lord deputed Veerabadra to help the sage.  Lord Veerabadra protected Sage Agasthya and also relieved the sage from the dosha.  He thus has His due place in the temple.  As sage Agasthya worshipped Lord here, He is praised as Lord Agastheeswarar and is the presiding deity of the temple
