The rough English translation of Kamasutra is pleasure (kama) treatise (sutra). In the West, since it was first (rather surreptitiously) translated and published back in 1883, the book has generally been associated with a series of beautiful, ancient illustrations of a couple determinedly coupling in a variety of fascinating — and often utterly improbable — positions; as essentially ‘the erotic counterpart to the ascetic asanas of yoga’.
