What happens to the Soul at death? Do we see the Soul leave the body? Although we don't, we know that is what causes death, that is why we cremate or bury a body. Where does the Soul go? If the Soul leaves the body, then it has to go somewhere and it doesn't travel through space to go somewhere. It just merges with the Spirit that is everywhere. The best way to understand how the Soul is a part of the Universal Spirit is to blow air into a balloon. Where do you get the air from? From the air that is everywhere. If you burst the balloon, where will the air go? Into the air that is everywhere. So does the Soul. The Soul is energy, is a power and we can feel that power not only inside us but we can feel that power all around us.
