The mauryan empire was white. The Arya were a scythian tribe who decided to settle in fertile farming grounds. They crossed into the Punjab and found small brown humanoids they called "dasa(trash)". They conquered the areas and set up the jati and varna systems. The Hindu religion is ancient scythian stories of ancestors. The true Brahman are one of the longest lasting and purest ties to our scythian ancestors along with the Nordic people's. The "caste" system was a way to prevent race mixing.
