The Tirukkural or Thirukkural (Tamil Name: திருக்குறள்), or shortly the Kural, is a classic Tamil sangam literature 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, it is known for its universality and non-denominational nature. It was authored by Thiruvalluvar.
Considered as chef d'oeuvre of both Indian and world literature, the Tirukkural 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 given by, such as Tamiḻ maṟai (Tamil veda), Poyyāmoḻi (words that never fail), and Deiva nūl (divine text). Translated to about 80 global languages, Tirukkural is the most widely translated non-religious work in the world. The work is dated to sometime between the third and first centuries BCE and is considered to precede Manimekalai and Silappatikaram, since they both acknowledge the Kural text.
