Arupadai Veedu.Six important temples of Subrahmanya
And the Thirumurukaatruppadai ,Sangam poem mentions Subrahmanya and this poetic work is on Subrahmanya.
Though it is dated around 3000 years ago, current dating of Poompuhar pushes the date of Sangam Literature back to about 16,000 years .
Though there are many temples for Lord Subrahmanya, six were classified as the Six Abodes that Channelize individuals to Godhood., Subrahmanya.
Thiruthani,
Pazhani,
Thitupprankundram,
Swamymalai,
Pazhamudhircholai and
Thiruchendur.
All are in Tamil Nadu.
One of these temples, Thiruchendur on the Eastern Coast of Tamil Nadu,India survived the Tsunami that struck Tamil Nadu.
Tsunami struck Tamil Nadu on 26 , December,2006.
The giant wave did not touch the temple and one could see it backing off, while it created havoc in the surrounding area.
‘the only major architecture in the area not to be damaged by the December 26, 2004, Indian Ocean tsunami? The waves destroyed everything around the temple but did not touch the temple itself. It is a fact many witnesses acknowledged...
A forum called Oceanographers.net contains a post in which a scientist claims to have solved the mystery. After research conducted at the site, the scientist discovered that the site’s geographic location had a major role to play in the safety of the temple from the waves. He noted that the location is such where even the tidal waves, which hit other parts of the city, do not touch, and that a natural elevation in the rocks broke the chain of the waves. But in the end the scientist did give credit to those who built the temple at the place for choosing the site properly and after a careful study.
A Scientific explanation?!
