Tirukkuṟaḷ (Tamil: திருக்குறள் also known as the Kural),
sometimes spelt 'Thirukkural, is a classic of couplets or Kurals (1330 rhyming Tamil couplets) or aphorisms.
It was authored by Thiruvalluvar, a poet who is said to have lived anytime between 2nd century BCE and 5th century CE.
Most believe he wrote Thirukkural in 30 BC which is part of Tamil Sangam Period.
 It is one of the Tamil books of Law.
The Thirukkural is one of the most important works in the Tamil language.
This is reflected in some of the other names by which the text is known: Tamil marai (Tamil Vedas);
poyyamozhi (words that never fail); and Deiva nool (divine text).
The book is considered to precede Manimekalai and Silapathikaram since they both acknowledge the Kural text.
Thirukkural (or the Kural) is a collection of 1330 Tamil couplets organised into 133 chapters.
Each chapter has a specific subject ranging from "ploughing a piece of land" to "ruling a country".
It preaches simplicity and truth throughout its verses.
