The Tirukkuṟaḷ (Tamil: திருக்குறள், lit. 'sacred verses'), or shortly the Kural (Tamil: குறள்), is a classic Tamil language text consisting of 1,330 short couplets, or kurals, of seven words each. The text is divided into three books with aphoristic teachings on virtue (aram), wealth (porul) and love (inbam), respectively. Considered one of the greatest works ever written on ethics and morality, it is known for its universality and secular nature. Its authorship is traditionally attributed to Valluvar, also known in full as Thiruvalluvar. The text has been dated variously from 300 BCE to 5th century CE. The traditional accounts describe it as the last work of the third Sangam, but linguistic analysis suggests a later date of 450 to 500 CE and that it was composed after the Sangam period.
