 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 ) , <unk> ( dancer ) , <unk> ( danseuse ) , <unk> ( bard ) , <unk> ( wandering performer ) and <unk> ( acrobat ) . Their body movements ( 6 Anga , 8 <unk> and 6 <unk> ) 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 <unk> and 26 Charis of the dance tradition . The discussion on dance movements is compiled by six categories – mimetic ( <unk> ) , delicate ( <unk> ) , vigorous ( <unk> ) , acrobatic ( <unk> ) , <unk> ( <unk> ) and graceful ( <unk> ) .
