The son who taught his father
Shiva has forgotten the meaning of the Pranava, the syllable Om. In the account the temple's website gives, the loss is the work of a curse laid on him by the sage Bhrigu.
Shiva sends for his son, Subrahmanya.
The son agrees to teach the father — on one condition. If Shiva wants the mantra, he must learn it properly, as a pupil learns from a teacher.
Shiva accepts. He stands before his young guru with his hands folded and his head bowed, and Subrahmanya teaches him the essence of the Pranava.
That reversal — the son as teacher, the father as student — is what the place is named for. Murugan here is worshipped as Swaminatha, and the hill as Swamimalai, because the son became the teacher of his father.
The temple's plan keeps the story in stone. The shrine of Subrahmanya stands on the hillock; the shrine of Shiva is below it.
The website does not cite a Purana chapter for the episode. Other retellings of the Pranava story — among them versions in which Brahma, not Shiva, is the first to be questioned about the syllable — are known to us only from encyclopedia summaries, and are not told here until they can be given from a primary text.
