Tirukkural also known as the Kural is a classic of couplets or aphorisms or Kurals composed in Tamil by Thiruvallur, who lived between the 2nd century AD and 6th century AD. It is one of the finest pieces of literature that has been produced by India. Tirukkural expounds on various aspects of life and is one of the most important works in the Tamil language. Even though exact period of its formation is doubtful, it was agreed upon by various scholars that Tirukkural was composed during the late Tamil Sangam period. It is also known as Poyyamozhi Tamil Marai and Daiva Nool.
