Tiruchy : 

Rare symbols have been discovered at the Lord Shiva temple at Alundur in Srirangam taluk in the district recently denoting the Brahmadarshana symbol, Manduka Diagram and Sulastone with plinth.

According to research team scholars headed by T L Subash Chandra Bose, the symbols were found at Shiva temple in Alundur as well as in some of the surrounding areas.

The scholars claimed they also found a trident with a base with the Tamil letter ‘Ka’ inscribed on the right side of one of the pillars in the temple. The symbols could date back to the 16th century BC, they said. Elaborating the significance of the Tamil letter ‘Ka,’ Subash Chandra Bose said that the alphabet refers the first true letter and also the first numerical number ‘one’. The root of letter ‘Ka’ is a cross between vertical and horizontal lines referred to as the ‘causation’.

“Ka represents Lord Param or Brahman (not Brahma). Lord Param is also symbolically indicated as an oblong with a cross at the center. It is a four square matrix (Pecaka diagram) which you can see in the Sulastone at Keezhakuruchi village stating about the Siva Temple — Jambukeswarar Akhilandeswari — in Thiruvanaikoil near Srirangam where the tree, the spider and an elephent attained moksha,” he said.

The Mayamata — the temple architectural manual — says the centermost four square in the 64 square matrix is the heart zone, where the Ka — Lord Param or Brahmam dwells. An interesting reference found in Chaandogya Upanishad (verses 4.10.4-5). Ka and Kha is Brahman. Below is the explanation or interpretation of it, he  said.
