The Rigveda is the oldest and most important source of material for India, Indo-Aryan, and even Indo-European history. It is a text which has been part of a hoary and widespread living tradition thousands of years old. Naturally, a text which has remained alive, as part of a living tradition, for so long cannot and should not be analysed without reference to what that tradition has to say about it. In the present volume, the author has confirmed emphatically that India was also the original homeland not only of the Indo-Aryans but also of the Indo-Iranians and the Indo-Europeans. The author has gone directly to the primary sources without any preconceived notions, and examined as well analysed the available information with the help of traditional tools of interpretation. In this present study, he has elaborated a historical analysis of the Rigveda on the basis of genealogies of composers of the hymns preserved in the Anukramanis or indices of the Rigveda.
