The materialists, they claim Aryan only from the bodily conception, but that is not the fact. Anyone who is advanced in spiritual life, they are called Aryans. Anarya-justam. Arjuna was chastised by Krsna that “You are talking like non-Aryan.” Anarya-justam. So non-Aryan and Aryan, what is the difference? The Aryan civilization means this varnasrama-dharma, four varnas, four asramas. And non-Aryan means there is no division. Everyone is one or equal. That is advocated now at the present moment.
