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.
Understanding transforms, it does not sublimate. If you understand, anger disappears and the same energy becomes compassion. Not that you sublimate: anger simply disappears, and the energy that was involved, invested in anger, is released and becomes compassion. When you understand hate, hate disappears and the same energy becomes love. Love is not against hate -- it is absence of hate.
Those who are not angry at the things they should be angry at are thought to be fools, and so are those who are not angry in the right way, at the right time, or with the right persons.
I know, to banish anger altogether from one's breast is a difficult task. It cannot be achieved through pure personal effort. It can be done only by God's grace.
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.
