What is "parisista"

( Devanagari: परिशिष्ट, "supplement, appendix") is the term applied to various ancillary works of Vedic literature dealing with details and elaborations not covered in the texts logically and chronologically prior to them: the Samhitas, Brahmanas, Aranyakas and Sutras.

Parisista works exist for each of the four Vedas. However, only the literature associated with the Atharvaveda is extensive.
