You are totally entitled to be angry and unforgiving towards people who hurt you as long as you don’t take revenge and hurt them in return.
Never feel guilty for being angry and upset with someone.
Your anger is sacred and real.
In this world of separation it is totally legitimate to be upset and angry.
When you cover it up with detachment, conventional good manners or haughty words about love, forgiveness and compassion, then your anger becomes very poisonous and perverted.
This type of undercover anger is what corrupts this world and kills your soul.
