The historical Bhagavad -Pyhäkaavat (Bhagavad Gita) is a collection of letters mostly written by Achaemenids´ vassals dating back to the pre-Roman Iron Age of Northern Europe. Letter writing begins in Greek Anatolia in 480 B.C.E. and continues in North Europe. Ancient Veda texts are astonishing, historical first- hand information about northern kingdoms established by the Achaemenid dynasty. Previously, it was not known that the Persian sphere of influence even extended to the territory of present-day Finland. Cyrus the Great was aptly titled ´King of the Four Corners of the Earth´.<br/><br/>The Achaemenids were a common factor between Vedic India and Vedic North Europe. Their power also extended to Caria and Ionia in Anatolia. These people spoke and wrote in the Carian or Arian language, the language that is called the Finnish Karelian dialect nowadays. <br/><br/>The Bhagavad Gita letters also provide valuable information about their ancient Baptist religion. Many of its features were transferred to modern religions.
