"What Books and Burials Tell Us" is a chapter in the NCERT Class 6 History textbook that discusses the types of Vedas and describes Rigveda in particular. The chapter also explains how historians study the Rigveda, the story of the Harappa and Mohenjodaro civilizations, and how the houses, drains, and streets of Harappa were planned. The chapter also discusses the evidence from burials that archaeologists use to find out whether there were social differences amongst those who were buried. For example, archaeologists found that in some burials, skeletons found were buried with pots, and the number of pots buried was more if the person had higher social status. The chapter also discusses the differences between the life of a raja and that of a dasa or dasi. A raja was a rich and powerful leader, while the dasa or dasi were slaves owned by people. The chapter provides exercises and questions to help students understand the concepts discussed in the chapter.
