The guy who posted as tallest skil on voat mentioned in one of his more thorough black pill posts that the earliest Vedantic religion was brought to northern India by Aryans, who over the millenia mixed with the southern indians. Those Arayans were the same group who spread into europe in several different waves, mixing with Indo Europeans to create the modern ethnic groups of Europe. First through Anatolia and Greece, and later through the Ukraine into western Europe creating various groups of Celtic and Germanic peoples.
