Commentary

The word "non-āryan" has a lot of scholarly controversy around it arguing whether the āryans came into the Vedic culture from outside or were a class of people within the Vedic culture. There is also a lot of misconception surrounding the word from the Nazi-era and the Nazi abuse of the word. It is just best to know that it was not flattering for someone to take on "non-āryan" qualities at the time the Bhagavad Gita was written.
