I should have also addressed your comment about being born again on earth.
This is an important topic and aspect of reality that few understand.

Reincarnation is possible but no one ever does reincarnate. Once you leave the earth and return home to “heaven”, you never want to leave again.
There is a reason it is called heaven and this place is called earth. If you return to heaven, why would you want to return to the earth?
Secondly, if you did decide you wanted to reincarnate, first of all, a lot of planning needs to go into coming back to earth. It is not a decision or a plan that comes easily.
It took a long time for you to incarnate this time and to possibly do it again, will take another long time because there are already thousands or millions or billions of other spirits that would like to incarnate for their first time.

So, with that in mind, think of what happened when you incarnated. Do you remember anything before you incarnated?
Do you remember all the things you did getting ready to incarnate?
Do you remember before you even knew that incarnation was possible?

No, of course you don’t. No one does, I certainly have no memory of my existence before I was born on earth.
That is because the moment that you are born onto the earth, your memory is wiped and you cannot remember anything.

So, that is what would happen to you before you incarnated again. Your memory would be wiped and you would not remember anything.
You would not know that you played guitar before, you may not even be the same gender or live in the same country or speak the same language.
You may decide to do something completely different.
You have no idea because you have no memory of your previous incarnation or anything before you were born.

So, everything that you learned this time is all gone, totally wiped out of your memory.
That doesn’t sound like a very good idea to come back to earth, does it?
That is the reason no one comes back, what’s the point?
When your incarnation is over, it’s time to return to heaven and continue on with your journey there and you have all your memories from your earthly incarnation.

Now, there would be a way to remember your previous life on earth but there is a problem, with your mind wiped, you would have to try and know that you can link with your higher self and the akashic record and then view your past life on earth. Then you would be able to see that you played guitar and then you could decide that you wanted to do that again but you are starting from the beginning of having to learn to play guitar again, buy all the gear and everything.
So, it is far better to just carry on with your life journey in heaven.

I hope that helps.
