Thirukural a world literature

"Tirukkural is the life, Tiruvasagam is the heart, and Tirumandiram is the soul of Tamil culture..." Swami Shivananda - On the Tirukkural

Thirukural written by Thiruvalluvar consists of three books, the first book on aram (the way or dharma), the second on porul (material or artha) and the third on inbam (joy or kama).

We could have come across lot of literatures, what special about this one ? Why should we call it as a world literature ?

The point which i can say simply about it is "Its a single literature which explains moral of life with different category, which the whole world can accept without any refute"

we say, geetha given to human by god
thiruvasagam given to god by human
Its only Thirukural, which is given to human by human

If you have any question how you should act/react, you can just refer Thirukural
I'm very much surprised and impressed about author Thiruvalluvar that he has the visionary of human evolution, long years ago. You can find out all statements suits all times and without loosing moral of life. His words are stronger in this literature it is really a great treasure for the whole world.

Little more info about literature, It was written in Tamil, author followed all the grammatical/rhyming rules. It has 1330 kural(statements), each kural has 7 tamil words 4 in 1st line, 3 in second/last line. Thats what amazing about the author.
