Why do we forget past lives

A--To remember would often not be of service in this life. We come to this life in intense focus to work through the experiences we picked out to guide us to understanding and knowledge. In many instances remembrance would be an emotional torture. In others due to our current awareness it might embarrass or cause shame, guilt, or horror, even intense pride. All of this and more would adversely affect AND effect our free will and become self limiting. Past life regression becomes important when lessons learned could help us progress and understand present circumstances and situations. It is during times such as this that people will often encounter a memory or dream of a time gone by.
