(The real brahmin is the one who:) ... has crossed beyond duality ...

He who knows me as his own divine Self breaks through the belief that he is the body and is not reborn as a separate creature. Such a one is united with me. Delivered from selfish attachment, fear, and anger, filled with me, surrendering themselves to me, purified in the fire of my being, many have reached the state of unity in me.
"I got this today," they say; "tomorrow I shall get that. This wealth is mine, and that will be mine too. I have destroyed my enemies. I shall destroy others too! Am I not like God? I enjoy what I want. I am successful. I am powerful. I am happy. I am rich and well-born. Who is equal to me? I will perform sacrifices and give gifts, and rejoice in my own generosity." This is how they go on, deluded by ignorance. Bound by their greed and entangled in a web of delusion, whirled about by a fragmented mind, they fall into a dark hell. Self-important, obstinate, swept away by the pride of wealth, they ostentatiously perform sacrifices without any regard for their purpose. Egotistical, violent, arrogant, lustful, angry, envious of everyone, they abuse my presence within their own bodies and in the bodies of others.
The man who gets angry at the right things and with the right people, and in the right way and at the right time and for the right length of time, is commended.
