Punyakashi's long penance by the southern sea
Punyakashi is the daughter of Mayasura. She goes to Kailasa and worships Shiva there, and she keeps worshipping him for three yugas before he appears and asks what she wants.
Her request is to be merged with Shiva for ever.
Shiva does not refuse. He explains time instead. He takes her up the scale of cosmic reckoning — from a year of 365 days, through the yugas, through a day of Brahma and a century of Brahma, through the great deluges — to a point where ten of Vishnu's deluges pass in a single second of Shiva's own time. Her wish will be fulfilled then.
Until that moment she has work to do. Shiva tells her to go to the shore of the southern sea and meditate there. Her hermitage will be called Kanyakshetra, or Tapah Sthala, the place of penance. She is to destroy wicked beings such as Banasura and relieve the people of them. And Shiva promises that he will come and stay with her there.
Punyakashi bows to him and goes south. On the shore of the southern sea she takes up a prayer necklace and a new name, Kanyakumari, and begins her penance.
The demon Bana has conquered the three worlds and rules his people wickedly. He sees her and wants her for his wife. He comes to her with his servants Durmukha and Durdarshana and asks.
She refuses him outright, and they fight. The battle ends when the Devi's discus, the chakrayudha, strikes Bana down.
The place where he fell is the Chakra Tirtha. The episode explains the name of the goddess, Kanyakumari, the name of the place as a kshetra of penance, and the sacred water on the shore, and it gives the shrine its defining image: a goddess who remains unmarried and waiting, on guard at the edge of the sea.
