Origin/History :-
Tiruvetkalam Paasupatheeswarar Temple is the 56th Thevaram Paadal Petra Shiva Sthalam and the 2nd sthalam on the north side of the river Kaveri in Chozha Nadu. This temple is situated in Chidambaram, also known as Thillai, which derives its name from the Thillai Tree (Excoecaria agallocha Linn) prevalent in the region. Historically, Chidambaram was known by various names such as Puliyur and PerumpaRa puliyur during the 7th to 8th centuries.
The temple, believed to be over 2000 years old, was originally constructed by the Pallava kings. Later, it was renovated by the Nattukkottai Chettiars. In ancient times, the area was densely populated with bamboo trees, and the historical name of this place is Moonkilvanam.
Puranic Significance :-
Arjuna, the renowned archer of Bharath, was advised by Lord Krishna to perform penance to receive the Pasupatha missile from Lord Shiva, despite already having many weapons from his father, Indra. Following Krishna's counsel, Arjuna came to a place dense with bamboo trees. Duryodhana, intent on disrupting Arjuna’s penance, sent the demon Mookasura in the form of a wild pig to thwart him. To counter this, Lord Shiva, accompanied by Mother Parvati and the Four Vedas in the guise of dogs, arrived as a hunter.
During the confrontation, both Shiva and Arjuna simultaneously shot arrows at the pig, leading to a dispute over whose arrow had killed the demon. This dispute escalated into a fight between Shiva and Arjuna. When Arjuna struck Shiva with his bow, the impact was felt throughout the world. Shiva, in response, tossed Arjuna with His toe, causing him to fall into the Krupa Kadaksham spring. Mother Parvati, enraged by Arjuna's assault on Shiva, was calmed by Shiva, who reminded her of the qualities of a loving mother and addressed her as ‘Sarguna,’ meaning someone with calm traits.
Arjuna was ultimately blessed by the touch of Shiva's feet and granted darshan with Mother Parvati, receiving the Pasupatha missile he desired. The scar from the bow-blow on the Shivalinga remains visible to this day.
