At the time of every creation, knowledge of four Vedas emanates direct from God and is originated in the heart of four Rishis in non-sexual creation.

In this Veda though the description of every worldly matter right from straw to God has been mentioned but it speaks especially about matters concerning science of the world. God has described qualities/nature of all materialistic articles of the universe.
