To seek to extinguish anger utterly is but a bravery of the Stoics. We have better oracles: 'Be angry, but sin not.' 'Let not the sun go down upon your wrath.'
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.
Compassion is not against anger. When anger disappears, compassion is. Compassion is not to be fought for; it is not against passion. When passion disappears, compassion is. Compassion is your nature.
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.
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)
If you strike a child, take care that you strike it in anger, even at the risk of maiming it for life. A blow in cold blood neither can nor should be forgiven.
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.
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.
