The Kama Sutra of Vatsyayana

Now these 'Kama Sutra' (Aphorisms on Love), written by Nandi in one thousand chapters, were reproduced by Shvetaketu, the son of Uddvalaka, in an abbreviated form in five hundred chapters, and this work was again similarly reproduced in an abridged form, in one hundred and fifty chapters, by Babhravya, an inhabitant of the Punchala (South of Delhi) country. These one hundred and fifty chapters were then put together under seven heads or parts named severally— 1st. Sadharana (general topics). 2nd. Samprayogika (embraces, etc.). 3rd. Kanya Samprayuktaka (union of males and females). 4th. Bharyadhikarika (on one's own wife). 5th. Paradika (on the wives of other people). 6th. Vaisika (on courtesans). 7th. Aupamishadika (on the arts of seduction, tonic medicines, etc.).
