What brings you peace?
When people listen to you, respect you for what you have done to them , gives you a lot of contentment and peace.
When you help people, respond to them kindly in spite of them shouting at you angrily, gives you peace.
Yes, it is difficult to be kind and compassionate ,especially to those who only want to disturb you. But staying calm in such situations only makes you stronger and the other person weak.
Regret only comes from negative reactions, positive reactions only give you peace when you think about it after sometime. So never ever underestimate the power of goodwill, kindness and compassion.
