Thirukkural, written by Sri Thiruvalluvar (1st century BCE) is one of the greatest works on ethical livingwas written in Tamil. It consists of 133 athikarams or chapters. Each athikaram consists of 10 kurals (rhyming Tamil couplets) thus making 1330 kurals in total.
Thirukkural is divided into three sections. Section one deals with Aram doing things, with conscience and honor, for the good of the less fortunate, the second discusses Porul realities or facts of life, and the third dwells on Inbam the pleasures that a man and a woman experience in the course of their relationship. It is claimed that this division of Thirukkural is based on the canonical dharma, artha & kama (trivarga) articulated in the Sanskritic classical texts.
