The Tirukkural or Thirukkural ( literally Sacred Verses), or shortly the Kural, is a classic Tamil text consisting of 1330 couplets or kurals, dealing with the everyday virtues of an individual. Considered one of the greatest works ever written on ethics and morality, chiefly secular ethics, it is known for its universality and non-denominational nature.It was authored by Valluvar, also known in full as Thiruvalluvar. The text has been dated variously from 300 BCE to 7th century CE. The traditional accounts describe it as the last work of the third Sangam, but linguistic analysis suggests a later date of 450-500 CE.
