Then what is an alien soul? As we all know, human beings are fundamentally a spiritual existence, and we are all human beings. Therefore, we all call other spirits different from our human spirits "alien spirits", and the knowledge of studying them is naturally called paranormal science. Some friends may ask, many times, we don't even know our own spiritual body. How can we study other spiritual bodies? In fact, our primitive spirit body is a pure state of "nothing". After the reincarnation of the day after tomorrow and the pollution from the outside world, it has already become a heterogeneous spirit body. Therefore, our research on supernatural science, of course, also includes our own research-because our present soul is not the real human soul.
