Sri Ketu Bhagawan Thiru Koll - Sri Naganatha Swami Kizilaperumpallam, Nagapattinam District, Tamil
This temple is dedicated to Lord Sri Shiva and is very small in size and is about three km from the Sri Budha temple situated at Thiruvangadu. This place is known as Kizha Perumpallam. There is a separate Shrine for Sri Kethu who is considered as Gnanakaraka who bestows knowledge and vairagya to people. The name of the Sri Shiva is Sri Naganathar Swamy and the goddess is Sri Soundarya Nayaki.
The devas and the asuras churned the paarkadal (Celestial Ocean) to get the Holy Nectar (Amrutham). Lord Vishnu decided to distribute it only amongst the devas and not asuras as the amrutham would make the asuras stronger and their atrocities will increase. When Lord Vishnu was distributing the Amrutham amongst the devas, at the behest of Sukracharya, one of the asuras, in the guise of a deva consumed the nectar. The Sun and the Moon noticed this and complained to Lord Vishnu. An angry Vishnu used his chakrayudham (discus) to cut the asura into two and threw them away. The head joined with a snake’s body to become Rahu Bhagavan. The body portion kept growing because the asura had consumed Amrutham. This later joined with the head of a snake and became Kethu Bhagavan. They prayed to Shiva to get rid of their sin and sought to be included as planets. Their wish was granted by Him.
However, Rahu and Kethu never forgave the Sun and the Moon. They cause eclipses as an act of revenge. Rahu is further classified as Nitya and Parva Rahu. Nitya Rahu keeps tugging at the Moon causing it to wax and wane, while the Parva Rahu swallows the moon causing the lunar eclipse. Kethu causes the solar eclipse.
Pooja: Picking up bad habits, property disputes and loss of property, humiliation, lack of Progeny, marriage obstacles are all due to Kethu dosham. This is the parihara sthalam to get rid of the Kethu dosham. He is believed to bestow the following on his devotees; good eyesight, gain in property, fame, vehicle, children etc. Devotees worship Kethu Bhagavan with red Lilly flower, by draping him with multi-coloured cloth and offering Kollu (Horsegram).
