The part of you that never dies
Reincarnation in some form or system is most likely to exist. The energy of the sole - the Ba can travel through the Universe as well as the spiritual world. The Ba is like the entire Cosmos eternal - without start nor end. Its just being.
The Ba is an energy bundle consisting of photons and energy strings organized in a very special way which is the core you. And in the free - not attached in a biological body, it is able to adjust its frequency level in order to pass between the different parallel universes that exists. Even the one in which everything is spiritual.
