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
