This book has two parts; in the first part we explore the possibility of Hindu Nagas migrating to South America and Central America and establishing Mayan, Aztec, Olmec, Inca and other civilizations. In the second part we read all about Rishis (seers), Asuras, Rakshasas (demons), Gandharvas, Apsaras and Kinnaras. There are lot of names of non-Divine names in the rig Veda and the Atharvana Veda. We have no satisfactory explanations for those words. I have collected as many names as possible and tried to give a Dictionary of Demons. It is only a beginning.
