I've got the question now. If this is indeed the way it always happens and one always lets all the things go in his afterlife, how can you explain the fact that the same traumatic events can be experienced from one physical life to another repeatedly? Logically, if one moves past his trauma in a life between lives, in his next lives the same trauma should never happen?!!??!? How come it can?
This is a good one

I think there's a saying, Religion always contradicts itself.
Really i think new-age was thought up by demons themselves, what a perfect trap for humanity

I will reply honestly here, even though I see this type of questions at a kinder garden level. And I don't mean by that that I'm at some higher level, but simply that I've learned a long ago that anything I read should be taken "cum grano salis".
From from I see, what I conceive as "trauma" someone else doesn't. Some people are insulted when you say certain things to them, while others are not, and don't even think about it. Thence, our reality is our perception of reality. And what is "happening" to us is our interpretation of outside events.
Of course we all agree that some events are harmful and we all agree they are traumatic, but the way karma threads are woven is not something we have insight too. In this life I've learned to accept two things about bad things happening: 1. if I hurt someone in my past lives the way I am hurt now, then it's ok for me to experience what's it like. And 2., we have a saying in translation it goes: from each bad event grows something good.
In short anything that is happening in reality is happening now, and all mystics agree to that. Past life, and the period in between lives from the point of reality, of action, of what you can do to change, is not a direction where you should put your efforts in order to gain peace, reconciliation or solution to any problem.
Past cannot be changed, but what can be is anyone's perception of what is true and real. If events seem to be reoccurring, it's because the perception is the same. You see what is in your mind.
It's like that story when they brought a peasant to the Louvre and when they asked him what did he see in the paintings he said: chickens.
I hope I'm clear as I don't expect you to agree with me.
