அகர முதல எழுத்தெல்லாம் ஆதி பகவன் முதற்றே உலகு.
As 'A' is the first of all letters, so the Primal One is first in the world.
The blank space of the unnamed God in Kural 1 became the most fought-over theological space in Tamil intellectual history. The rationalist movement (Periyar) said: the blank space proves there is no God here. The Shaiva tradition said: the blank space is Shiva, unnamed because he is beyond names. The Jain tradition said: it is the tirthankara. The Christian missionaries of the 19th century said: it is God the Father. Each reading tells us more about the reader than the text.
The first word: 'Akara' (அகர) — the letter A. The Kural begins with language, not God. It begins with the system (the alphabet) and uses it to argue for a first principle (the Primal One). This is logic, not prayer. The 'Primal One' (Bhagavan — பகவன்) is unnamed — deliberately. No Shiva, no Vishnu, no specific theology. Just: something was first, as A is first. Commentators spent centuries filling in who that first being was. Thiruvalluvar left the space blank.
