 Rhetoric is discussed in chapter 4 @.@ 17 of Manasollasa . The text dedicates over 450 verses in chapter 4 @.@ 18 to dance and describes various types of dance forms , musical instruments that go with dance performances , and the various occasions when dances were celebrated . The text discusses six types of performers , their characteristics and their roles – Nata ( actor ) , Nartaka ( dancer ) , Nartaki ( danseuse ) , Vaitalika ( bard ) , Charana ( wandering performer ) and Kollatika ( acrobat ) . Their body movements ( 6 Anga , 8 Upanga and 6 Pratyanga ) are explained in the text with their significance . This discussion is similar to that found in Natya Shastra , a Sanskrit text composed around 1st @-@ century BCE . The text thereafter presents the 21 Sthanas and 26 Charis of the dance tradition . The discussion on dance movements is compiled by six categories – mimetic ( natya ) , delicate ( lasya ) , vigorous ( tandava ) , acrobatic ( visama ) , ludicrious ( vikata ) and graceful ( laghu ) .
