Many a times in our life we would have thought why all this is happening to us. It is because we might have given the evildoers starring roles in our life drama, but to them,we might just be someone who got in their way. They pursued their goal without considering the damage caused by their actions because they become blind to realities.
They probably rationalized what they did wasn't wrong, or that they had no other option but to do what they did. People who harm others are usually in dreadful emotional states. They are under such pain, that all they have to give to others is pain
By realizing this, taking the actions of others less personally, and changing your thoughts about these actions, you can choose not to give your energy away to other people. You can lessen the negative impact that hurtful actions have on your emotional state. This truth will help you advance on the road to compassion and forgiveness.
