In the march towards Truth, anger, selfishness, hatred, etc., naturally give way, for otherwise Truth would be impossible to attain. A man who is swayed by passions may have good enough intentions, may be truthful in word, but he will never find the Truth.
The devil comes in many guises-anger in the form of justice-passion in the form of duty. When it first comes, the man knows and then he forgets. Just as your pleaders' conscience; at first they know it is all Badmashi (roguery), then it is duty to their clients; at last they get hardened.
Somebody insults you and you feel anger. Don't miss this opportunity; try to understand why, why this anger. And don't make it a philosophical thing. Don't go to the library to consult about anger. Anger is happening to you -- it is an experience, a live experience. Focus your whole attention on it and try to understand why it is happening to you. It is not a philosophical problem. No Freud is to be consulted about it. There is no need! It is just foolish to consult somebody else while anger is happening to you. You can touch it. You can taste it. You will be burned by it.
One cannot completely get rid of the six passions: lust, anger, greed, and the like. Therefore one should direct them to God. If you must have desire and greed, then you should desire love of God and be greedy to attain Him.
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!
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.
I could not for my soul distinguish ever the distinction between "religious anger" and "commonplace anger", "religious killing" and "commonplace killing", "religious slandering and irreligious", and so forth.
To be angry is to yield to the influence of Satan. No one can make us angry. It is our choice. If we desire to have a proper spirit with us at all times, we must choose to refrain from becoming angry. I testify that such is possible.
