"The Atharvaveda stands apart from other Vedic texts. It contains both hymns and prose passages and is divided into 20 books...This text is an extremely important source of information for practical religion, particularly where it complements the Rig Veda. Many rites are also laid down in the “Kausika-sutra” (the manual of the w:Vishvamitra:Kausika family of priests) of the Atharva Veda."
