At Thirunageswaram near Kumbakonam in Tamil Nadu, the Naganathar temple is the Navagraha Sthala sacred to Rahu, the shadowy northern lunar node. Shiva is worshipped here as Naganatha, and the temple is a Paadal Petra Sthalam of ancient renown. It is famed for a daily wonder: during the Rahu Kala worship, the milk poured over the image of Rahu is seen to take on a bluish hue.
Devotees throng here to propitiate Rahu and remove its doshas, seeking relief from obstacles and the fulfilment of delayed hopes. Thirunageswaram is the shrine of Rahu among the nine.
