Do you recall the story of the young Yogi in the Mahâbhârata who prided himself on his psychic powers by burning the bodies of a crow and crane by his intense will, produced by anger?
People seem to fight about things very unsuitable for fighting. They make a frightful noise in support of very quiet things. They knock each other about in the name of very fragile things.
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.
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.
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.
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)
