We praise a man who feels angry on the right grounds and against the right persons and also in the right manner at the right moment and for the right length of time.
If we ourselves remain angry and then sing world peace, it has little meaning. First, our individual self must learn peace.
This we can practice. Then we can teach the rest of the world.
Of ill-temper there are three kinds: irascibility, bitterness, sullenness. It belongs to the ill-tempered man to be unable to bear either small slights or defeats but to be given to retaliation and revenge, and easily moved to anger by any chance deed or word. Ill-temper is accompanied by excitability of character, instability, bitter speech, and liability to take offence at trifles and to feel these feelings quickly and on slight occasions.
She speaks poniards, and every word stabs: if her breath were as terrible as her terminations, there were no living near her; she would infect to the north star. I would not marry her, though she were endowed with all that Adam bad left him before he transgressed.
Evil company is always to be shunned; because it leads to lust and anger, illusion, forgetfulness of the goal, destruction of the will (lack of perseverance), and destruction of everything. (Narada Bhakti Sutra)
The man who gives way to anger, or hatred, or any other passion, cannot work; he only breaks himself to pieces, and does nothing practical. It is the calm, forgiving, equable, well-balanced mind that does the greatest amount of work.
If there be devils, would I were a devil, To live and burn in everlasting fire, So I might have your company in hell, But to torment you with my bitter tongue!
The man that is dominated by Anger Doth not know what is seemly and seeth not the Law; That man whom Hate doth accompany, Becometh like unto murky darkness.
