The Kama Sutra, written in Sanskrit sometime between 400 BC and 200 AD, describes practical aspects of sex as well as the philosophy of love and desire. It is an ancient Indian Hindu text written by Vātsyāyana and widely considered to be the standard work on human sexual behaviour in Sanskrit literature.
A portion of the work consists of practical advice on sexual intercourse. "Kāma" which is one of the four goals of Hindu life, means desire including sexual desire the latter being the subject of the textbook, and "sūtra" literally means a thread or line that holds things together.
The Kama Sutra is not exclusively a sex manual; it presents itself as a guide to a virtuous and gracious living that discusses the nature of love, family life and other aspects pertaining to pleasure oriented faculties of human life.
Kama Sutra is presumed or depicted as a synonym for creative sexual positions; in reality, only 20% of Kama Sutra is about sexual positions.
