When she tried to move the basket it got struck to that place, as she tried frantically to move it, a crowd gathered around her. Goddess Mariamman entered into the body of the small girl and indicated that her sculpture is buried here. She ordered them to dig the place to bring out the sculpture and consecrate it.
As ordered the priests digged the place and brought out the sculpture but they placed it in the temple inside the city.
