No, says Bháradvája, anger is the characteristic of a righteous man. It is the foundation of bravery; it puts an end to despicable (persons); and it keeps the people under fear. Anger is always a necessary quality for the prevention of sin. But desire (accompanies) the enjoyment of results, reconciliation, generosity, and the act of endearing oneself to all. Possession of desire is always necessary for him who is inclined to enjoy the fruits of what he has accomplished.
