The Atharvaveda is composed in Vedic Sanskrit, and it is a collection of 730 hymns with about 6,000 mantras, divided into 20 books. About a sixth of the Atharvaveda text adapts verses from the Rigveda, and except for Books 15 and 16, the text is in poem form deploying a diversity of Vedic matters. Two different recensions of the text – the Paippalada and the Saunakiya – have survived into modern times. Reliable manuscripts of the Paippalada edition were believed to have been lost, but a well-preserved version was discovered among a collection of palm leaf manuscripts in Odisha.
