When Pandavas were in Exile, Arjuna followed the advise given by Kowmiya Saint to worship Vilvavananathar, Arjuna was blessed with Pashupathaasthram by Vilvananathar which he used during Mahabaratha War. Another famous story is, when Sage Thirugyanasambandar along with his disciples visted this place there was cyclone and he rowed the Boat without the Paddle by singing the verse "Kottamae Kamazhum" and by Gods Grace reached the other side of the bank and worshiped Vilvavananathar, hence the name "Odampokiyaaru"
Did Arjuna ever used his Pasupathasthra? i dont think so...if I am correct, its the most destructive weapon which when used will destroy the entire world....must be our modern day nuke.. so I dont think he ever used it.
Seeing the names of the ambaal(Azhagiya Naachiyaar), i guess its a temple dedicated to perumal. But i guess Pasupathasthram was given to Arjuna by Shiva. Pasupathy also refers to Lord Shiva. So, i got a little confused. Can someone enlighten me on this? Please pardon my ignorance.
