The state exists for man, not man for the state. The same may be said of science. These are old phrases, coined by people who saw in human individuality the highest human value. I would hesitate to repeat them, were it not for the ever recurring danger that they may be forgotten, especially in these days of organization and stereotypes.
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.
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.
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.'
