A group of bloggers, most linked to this blog, decided to post on the Myth of Guilt. Many of them put quite a lot of work into the project and wrote well. I simply have too much to do at this time but I will throw up a few comments for general consideration.
Our emotions are tools of self-discovery. Some of them we experience in positive ways others negative. Humans being what they are tend to learn from the negative. Guilt is one such negative emotion, anger (you didn't live up to my expectations), jealousy (you slept with X but you BELONG to me) and fear (I won't get x or I will die) are other examples of such things.
The trick is to not pass them off as some creepy bogey man or creation of the church. The trick is to learn from them. Got Guilt? Find out how you failed in your expectations of yourself. You can blame anything else you want but a magician will turn inward sooner or later. And when they do, they will learn how they failed themselves.
The myth is that guilt has no purpose.
The reality is that it is used against you by outside forces like your mother and the church.
The truth is the third thing. Guilt's purpose is showing you how you harmed yourself.
