Neither. We do reincarnate, but not right away. We are allowed to rest between lifetimes. When we leave this physical body, we meet with friends and loved ones whom we missed, then we meet with our spirit guides and discuss the lifetime we just lived. We are our own judges and juries. We decide for ourselves what our next step will be. Our guides do not intervene with our free will, but they will help us weigh the pros and cons of our previous decisions and actions so we can decide for ourselves what is best. We then spend time in a spiritual realm that resonates with our own soul's frequency with others of like expression and continue our spiritual education until the stars are aligned astrologically perfect for us to reincarnate again and continue our studies/experiences on the physical plane. It is neither heaven nor hell, it is what we ourselves decide.
