Many people struggle with the painful feeling of shame.  Perhaps we were told as children that we "should be ashamed" of something.  Perhaps we suffered mistreatment that we interpreted to mean we were not worthy of love and care.  Perhaps we did things for which we harbor shame.  Shame is nothing more than a negative thought about ourselves.  As we understand that people are always doing what makes sense to them at the time, given their level of consciousness, we realize that there is nothing to be ashamed of.  We can see beyond negative situations and learn from them, but there is no shame in being human.
