Shiva came to Muruga and asked him to release Brahma from imprisonment. Muruga refused to release him stating Brahma was unaware of the meaning of the Om - (Pranav Mantra-Tamil: ௐ AUM). Shiva asked Muruga to explain the meaning and Muruga extolled to Shiva the meaning of Om. Shiva behaved like a student to a teacher, listening with rapt attention from his son, giving Muruga the name "Swaminatha Swami". The meaning of this name is "The Teacher of Shiva". Following the legend, the shrine of the son Muruga is atop the hillock, while the father Shiva's shrine is located at the basement.
