அகர முதல எழுத்தெல்லாம் ஆதி
பகவன் முதற்றே உலகு.

Am planning to give the meaning and translation in english, so that it will be useful for non Tamils..

A, as its first of letters, every speech maintains;
The “Primal Deity” is first through all the world’s domains.
As all letters have the letter A for their first, so the world has the eternal God for its first.
