Some people have a tendency to seek to blame others for the results of the decisions they made. It is how they delude themselves into believing they are not responsible for their actions. They are also fond of holding people accountable for things beyond their control.
This is the ultimate blindness as they have disconnected results from actions and entered a dream world. As long as they remain in that dream state nothing will change.
It takes great courage to examine ourselves and be honest in accepting responsibility for results. When we have done that then we can start to master change instead of being at the whim of change.
Knowing ourselves is our hero's quest and rising above our errors leads to wisdom. With wisdom we finally gain perspective.
