After you die I believe you do spiritual work on yourself on the other side. We continue there just as we are now basically. My dad and stepdad both died and my dad was doing work on himself over there and needed my forgiveness. I informed him there is nothing to forgive then realized he needed love and light and prayers to help him as he was dealing with some unfinished business and guilt. I wished for him to release the guilt of whether or not he was a good father to me.
Our prayers and love help those on the other side to progress. It is just as useful here as there.
So, I do not believe we automatically incarnate again. I know I do not, nor has my family members. It is not best to rush back here. I also believe your desires and things you yearn for or lessons unfinished etc. go into the planning of your next life.
