Udog had a magnificent quote. I shall share in part. "...People who ignore or resist their feelings often end up obsessed with them..." Jack Morin
I believe that absoluely we must aacknowledge this emotion called anger. However, not to act irrationally. That is a major feature of what i think. Do not give in and with a possession of anger.
With anger comes intolerance and half the battle is lost. However, with correct reflection, sifting out the distortions in reason and logic that afflict us all, we may begin to understand one another.
Anger is in a sense a temporary psychosis. There are elements of reality. There are even more projections of one's own unfinished business of a psychological stance
and unresolved conflict. This is a danger, we can project unfished issues we have inside of our process with thinking.
“Events take their course, it is no good of being angry at them; he is happiest who wisely turns them to the account.” Euripides 480-406 BCE
