The Vedas are the most ancient and comprehensive book in the recorded history, covering almost all the aspects of society. There are more researches covered in the Vedas than in any other book. Greece is said to be the cradle of European culture while the Vedas originated approximately 8000 years before. The origin of language, grammar, politics, caste system, the arrangement of society, etc., can be traced to the Vedas.
The Vedas can be read for different purposes, as they are capable of giving more messages than one can imagine. In fact it is impossible to understand everything they say and why do they say what they actually say. Majority of the Indians regard them as revealed books because no human being could have been so wise as to cover all themes and subjects, besides all the aspects of human life as they do.
