Well, I believe I will come as a new person, and will not remember anything from my previous lives.
I also believe I carry friendships/issues with people from my previous lives, things that I have to deal with in my current life.
Have you ever asked yourself, WHYYYY is this happening to me? WHYYYY is this person so annoying to me? I dont think anything happens in life for no reason. I believe life is made of actions and consequences.
I believe that this life I have is to get better as a human being, fulfilling my own path for this life.
I believe we started as little things, evolved and evolved and will always evolve
My grandmother was American Indian and in this culture, the body is burned when you die. This is said to release your spirit so it can travel to the spirit world and join the rest of your family there. They also believe a new star shines in the sky when you reach this world. As for coming back after death, anything is possible. There is nothing to prove this is true or not true.
I believe after we die our spirit can be born again in a new world. However, if you trap this spirt in a box in the ground it can't be set free to find the new spirit world. Pople needs to have their spirits released so they can travel freely to the new spirit world where they will find peace and happiness. This is what I was taught and this is what I think will happen when we die.
