Thiruppaasoor (திருப்பாசூர்) village is located about 50 kms from Chennai on the road going from Thiruvallur to Thiruthani and is about 7 kms from Thiruvallur Railway Station.
Thiruppaasoor has a vast and beautiful temple for Lord Shiva. The main deity here is called Sri Vaaseeswarar and Goddess Sri Thankaadhali (தன்காதலி) Ambaal.
Thiruppaasoor got its name from the ancient Thamizh word ‘Paasu’ (பாசு) which means Bamboo. It is said that the entire place was a bamboo forest during ancient days. Once the local hunters saw a cow pouring its milk on its own in the bamboo forest and they dug up the place to find this beautiful Shiva Lingam.
While people dug up the place, an axe like tool which was used to dig the ground hit on the Shiva Lingam and created a scar on Him. The axe like tool was called ‘Vaasi’ in Thamizh and hence the Lord here is called as Sri Vaaseeswarar.
It is also said that, Karikaal Chozha, who was an ardent devotee of Lord Shiva had to wage a war against Kurumbars who were troubling him. Some Jain saints, who were supporting Kurumbars, made a serpent attack the king. Karikaalan surrendered the Lord here and prayed for rescue. Pleased with his prayers, Lord Shiva tamed the serpent and saved Karikaalan.
