2. Thirumal bridged the sea with mountains and completed his task
3. he levelled the sea
4. Thirumal blocked the sea
5.Built by vishnu who held a bow
6. after killing the demons with his chakra, thirumal built
Intrestingly, Appar peruman does not mention the Ravana lifting kailsh episode in this thevaram and in all the 11 songs, he is repeating that the temple is built by vishnu who came as Rama.
