Anger can be controlled. We cannot stop anger altogether, but if we simply become angry with those who blaspheme the Lord or the devotees of the Lord, we control our anger in Krishna Consciousness. Lord Chaitanya Mahaprabhu became angry with the miscreant brothers Jagai and Madhai, who blasphemed and struck Nityananda Prabhu…. One should be ready to tolerate all insults to one’s own self, but when Krishna or His pure devotee is blasphemed , a genuine devotee becomes angry and acts like fire against the offenders. Krodha, anger, cannot be stopped , but it can be applied rightly. It was in anger that Hanuman set fire to Lanka, but he is worshipped as the greatest devotee of Lord Ramachandra. This means, that he utilized his anger in the right way. Arjuna serves as another example. He was not willing to fight, but Krishna incited his anger : “You must fight!” To fight without anger is not possible. Anger is controlled, however, when utilized in the service of the Lord.His Divine Grace A.C. Bhaktivedanta Swami Prabhupada In ‘The Nectar of Instruction’, Text – 1.
