But there are times when we remember our actions in this life that make us feel uncomfortable about ourselves. We know those actions accrued karma that needs to be cleaned up. For example, I remember when I was about four years old. I was cruel to another child on the playground. That has stayed with me my entire life. It was unnecessarily mean and even to this day I regret it. So now I go out of my way to not make that mistake again.
I can also remember times when I was charitable and forgiving as a little child. Those were actions that generated good karma. I was kind to a child who felt she was an outcast. I comforted a crying child. So even though those actions were more than a half a century ago, I still feel good about them.
The only connection between karma and memory would be that memories help us to refrain from repeating actions that bring bad karma. And memories can also remind us of how good it feels to do kind things for others and ourselves.
