Now, it has become a common word, Āryan, but originally it is Sanskrit word. And ārya means one who is advanced, or one who is civilized, one who knows, one who has knowledge. Then he is called ārya. In the Bhagavad-gītā you'll find, when Arjuna declined to fight, Kṛṣṇa condemned him, "Oh, you are just like talking like a non-Āryan, not Āryan."
So we all belong to the Āryan family. Historical reference is there, Indo-European family. So Āryan stock was in the central Asia. Some of them migrated to India, some of them migrated to Europe. And from Europe you have come. So we belong to the Āryan family, but we have lost our knowledge. So we have become non-Āryan practically, because we do not give importance to the spiritual side of life. The Āryan means one who gives importance to the spiritual side of life.
And what is that importance? The spiritual side importance-giving means one has to see how much important this human life is. Because in the human form of life the spirit soul, although it is conditioned by material, I mean to say, encagement, it has developed it's consciousness by gradual evolution. This evolution theory is there in the Padma-Purāṇa. There is actually evolution from lower, I mean to say, status of life beginning from the aquatics, small, then, I mean to say, plant life, then germs' life, then birds' life, then beast life, then, I mean to say, human form of life, then civilized human form of life.
