"When we compare the bandhanrtta found in Nartananirnaya with the bandhanrtta practiced in the Odissi style, we find striking similarities. The bandhanrtta of Nartananirnaya requires combination created out of a base of sixteen karanas or short dance sequences, the bandhanrtta of Odissi requires seventeen. These karanas are extremely difficult to perform because of the physically demanding nature of their constituent movements and their rigorous design. As a result they are not commonly practiced."
