Lord Muruga imprisoned Brahma who was not able to tell the meaning of Pranava. On learning about this, Lord Shiva sent Nandi to retrieve Brahma. Then Shiva came to Muruga in person and got Brahma released by explaining to Muruga that the work of Creation had been affected due to the imprisonment of Brahma. When Shiva punished Muruga for his reckless action, Muruga dug Velayutha theertham to worship Shiva. The lingam, installed by Muruga is at the western part of the inner prahara.
