Human being means when he’s civilized, cultured, then he’s human being. If he’s not civilized, if he’s not cultured, simply having two hands, he’s animal.

So that culture begins, civilized, in the Aryan families. Therefore they are called Aryans, “advanced.” Aryan means advanced. People want to group themselves in the Aryan family. Just like Hitler, he declared himself only, “The Germans are only Aryans, and Jews are not Aryans,” like that. You can manufacture. But real Aryan means one who is advanced in spiritual consciousness. He is Aryan. Not a class of men. Aryan means he’s advanced in spiritual consciousness. The Aryan civilization is so eulogized because in
the Aryan civilization there was Vedic culture. That is Aryan.
