As the name suggests, the artwork in this deck takes some of the sex positions from Mallanaga Vatsayayana's Kama Sutra and applies them to the 78 cards of the tarot.
From Lo Scarabeo
According to legend, the Kamasutra was created by the Indian god Shiva who, overwhelmed by the joys of sexual experience, wrote a servant a treatise on erotic art. Inspired by the original Kamasutra, this deck is meant to aid seekers in their own quest for enlightenment through the senses.
Catching the flavor of 17th and 18th century Indian art, this deck blends its explicit sexual images into the Tarot model. A collection of such art is rare and valuable, making this a wonderful collectors deck. Experienced Tarot users may find specific and unique times to read with this deck.
From Aeclectic Tarot
The Kamasutra Tarot is based on the “textbook of desire” best known as a catalogue of sexual positions. The cards are indeed graphic, but are intended to reflect fourth century attitudes towards sex rather than modern Western views. The imagery across the cards is also deliberately repetitive, so that the subtle cues of posture and body language of the couple are more obvious.
