The Kamasutra of Vatsayana
by Richard F. Burton (Tr.) and John W. Spellman (Introd.) and Santha Rama Rau (Foreword)

Written with frankness and unassuming candor, the Kama Sutra remains one of the most readable and enjoyable of all the classics of antiquity/ A work of philosophy, psychology, sociology, Hindu dogma, scientific inquiry, and sexology, the Kama Sutra's importance is so great that it has at the same time both affected Indian civilization and remained an indispensable key to understanding it.
