I have discarded many beliefs on the road to maturity and replaced them with others. I do still make a wide berth when getting into bed to avoid being grabbed by the bogeyman-some beliefs die hard. The complexities of life, loss, new beginnings, birth, have altered or changed many of my prior beliefs.
I have discarded guilt as it is a soul-eater and non-productive. I accept responsibility for my actions but no longer tread the murky waters of self-flaggellation, having learned that most of us do the best we can with what we have to work with.
Another belief to hit the waste can is judgement. Painful life lessons have shown me that judging is an act of vanity, and an impropriorty, and I do not have the credentials to judge. So I try hard not to do it.
My outlook on personal relationships with my Creator has changed as well. We had a few bad years, Him/Her and I over the taking of my child, but when my own life was spared, the rift was repaired. Near death does that to people. My relationship now is an ongoing attempt to be part of the whole-I am God, God is me-we are one. It is not easy, since I am the flawed part of the whole.
