God said:
Baggage you carry with you is one thing. The concept of karma in the world is another. The difference may be subtle, yet the difference is momentous.
Yes, you may keep carting baggage from the past. Why would you keep dragging the past along with you on your next journey? You are smarter than that. Why would you go to all that trouble. For Heaven's sakes, why would I?
I wouldn't.
Do I teach you that you are a hapless victim of the past, that karma is your pay-pack, that retribution coming back to you to haunt you, that the past won't let you start over fresh, that the past follows you, even chases you, that you can't escape it, that a deed the person you once were committed is now marked on your back with a skull and crossbones, that, tut tut, that you can't do anything about leaving the past but to face the music?
Regarding this theory of karma, no one minds the karma of good deeds that you don't remember yet are considered responsible for. This is a horse of a different color!
By and large, karma is thought of as consequences for regrettable behavior. You may be an entirely wiser person now, yet somehow, still your hands are slapped from the past. If you were unkind to someone, one way or another, someone will hand you back the unkindness you gave even millenia ago. Tit for tat. That's it. There is nothing you can do about it. You earned this karma, and now it's time for you to pay the piper so be good from now on cuz so you won't have to walk in fear later.
