What is the Kama Sutra really?

The Kama Sutra is an ancient Indian treatise dedicated to topics of sensuality, emotional intimacy, desire, and love. Initially, it contained no images, only 64 sexual positions, which were called 'arts'. The author of the treatise, Vatsyayana, believed there are 8 ways of making love, with 8 positions in each. The Kama Sutra refers to sexual relations as 'divine union'. It was believed that there is nothing indecent about sex, but engaging in it frivolously is sinful.
