I don't believe in any deity. But I do believe in reincarnation. I believe a soul is given a choice to stay on earth as a ghost or be reincarnated, so I don't believe the reincarnation has to happen right away if the soul doesn't wish it. I am also a full believer in karma.
I believe that when we die a number of things could happen. I believe in God, so when we die God chooses where we will go. If we are saints we go to heaven, if we were horrible and commited bad things (really' really really bad things) we go to hell, and if we made mistakes and asked for forgiveness we go to Purgatory where our souls are cleansed before we go to Heaven. I believe that there are lost sould that roam earth, a.k.a. ghosts. I don't believe that souls travel from person to person, or from person to animal. No offence, that just my beliefs :)
part of me wants to believe the soul has a choice in what happens but the other part of me doesn't think it does... I do believe in karma though that if you make too many negative actions you will get reincarnated in to a life where you experience the full circle of those actions.
I believe in god as like the laws energy and cycles of the universes rather than a single being. As everything is part of the universe then everything in a way is part of god.
When we die I believe in reincarnation but I think there are different types. There is the reincarnation of your body with the earth, and then different kinds of soul transfer which could either be in to another being in our universe/any other universe or I think the soul could be recycled through the universe and used as pure energy for something like fire or electricity... pretty much becoming completely one with the major powers of the universe.
I do believe in other beings such as ghosts and angels/demons that we don't usually see/comprehend. I think it's because most of us aren't developed enough to experience them beyond when they directly affect our lives.
