Since it's obvious we messed up in our previous life even if by just making a wrong choice, are we born a clean slate? We recall no past life memories/ experiences, or DO WE? Does our subconscious mind hint at a previous life? Do our dreams hint at past life experiences? Are humans born 'sinless'? If nobody is perfect except God, we are born imperfect (spiritually)?
1. Messed up? Using what criteria? As a set of criteria is required to say "messed up" or "not messed up".
2. Are we born a clean state? Who are "we" that's being referred here?
Let's use again a metaphor for easy understanding.
The forum avatar Sarah cannot and do not have another avatar.
When she was born here, she has no previous post, no 'karma' point. Everything reset to zero.
And then let's say the forum admin blocked the account.
That might spell the end of Sarah, on this webforum.
Does Sarah 'messed up'?
It depends using what criteria that you'll use to put such label on "Sarah".
Depending on the criteria, you can say she does, you can say she does not.
Behind the forum avatar Sarah, there's a human consciousness.
Having one of his/her forum avatar 'dead', he/she has some options:
1. Doesn't mind about it at all, and move on. Either to another forum or decided not to join other forum at all. Just move away from this web forum, as he/she think that all that she needs from this web forum has already being fulfilled, or he/she just grow sick and tired of this web forum.
2. Rejoin this webforum, due to some reasons, but "Sarah" is unavailable, if he/she wanted to do that he/she need to create another forum avatar. So let's say he/she decided to create a forum avatar named "Abraham" this time around.
Abraham will start out from 0, a clean 'slate' as you called it, no karma points, no previous post.
So it's not "Sarah" being reborn into this forum, it's "Abraham" now.. albeit behind the avatar is the same consciousness.
It's the 'consciousness' that's 'reborn' or better word will be identifying his/herself to be "Abraham" inside this forum, and no longer identifying his/her self as "Sarah".
Perhaps the 'consciousness' think that he/she still have things to do / say or learn from this webforum, and would like to take another 'shot' at it.
The 'criteria' of whether 'Sarah' messed up (or not) during her active time on this forum is set by the consciousness him/her self. And so does the 'judgement'.
That's why the criteria that you use to judge others, will be used also for your own self, by your own self.
And if you have no criteria to judge others, you will not be judged as well by your own self.
