Formulating proof for the existence of the spiritual world is not so easy. First, one should draw logical conclusions from the laws and principles according to which the physical world was created. Then, use the experience of people who gave us testimonies about the spiritual experiences experienced. In the end you have to be like a detective or investigating judge who, out of minor facts, sometimes from insignificant events and few evidences for the existence of something elusive, must put together a picture of the truth about the phenomenon under investigation.
The logical conclusion from these analyzes should be the statement that the spiritual world is a spiritual reality destined for life for all spiritual beings. It should be not only our ultimate goal, but also the most important part of our eternal life, something like our own, peaceful home for forever, for eternity.
While the physical world is known to every human being, the spiritual world is not understandable to everyone. It is as if separated from our reality, because it has its own reality, other than ours. However, these two worlds in the original intention of the Creator were not supposed to be separate spheres, as it is today. Their proper state is full harmony and coexistence, which can be described as the initial reality. The spiritual world, from the earthly point of view, can be in some sense an overlay on the physical world, but an overlay unbelievably larger than the physical world. Therefore, one can rather say that the physical world is a pad for the spiritual world. In this relationship between them, the spiritual world has an absolutely superior role, which I emphasize in this whole study. It should also be noted that originally, the Creator intended free energy and information exchange between these worlds.
Of course, the spiritual world is not visible to human eyes, just as our thoughts and feelings are invisible and everything that has a spiritual nature. Time and space is what fundamentally differentiates the physical world from the spiritual world. In the latter the time does not end in an earthly sense and is not needed to overcome space. While in the physical world every place is a point in space, the concept of place does not exist in the spiritual world. Being in it has a different dimension, a dimension of omnipresence, that is, it is not subject to any physical limitations. For us, adapted to life in the physical world with numerous limitations, it is unimaginable. Therefore, in order to understand the functioning of the spiritual world, we need to change our "physical" understanding of time and space and the perception of this transcendent environment by our senses. It requires a special state of focus in which we silence the physical senses and let our thoughts float freely.
Usually, it is difficult for us to imagine a linear infinity, that is, directing thoughts into an infinite past or future. It is even more difficult to imagine the infinity existing on an unlimited level, and the worst we deal with the spatial limitations represented by the entire universe. The same problem arises with an understanding of the lack of passage of time.
As I have pointed out above, the world has no dimensions, structures or directions beyond time and space, and there is no time in it. This is the initial definition of the spiritual world. In the meantime, we must locate specific spiritual entities in this world, such as angels or spiritual persons who have already ended their physical lives. The most difficult, and perhaps even impossible, is to localize God there. The reason is His total ubiquity, both in the form of His ubiquity from which the physical universe arose, and in the form of His Spirit containing all the laws and principles that govern the universe.
All spiritual beings can be limited only by their personality, or the level of intelligence, will and affection. Knowledge is the manifestation of intelligence, and this is different in individual spiritual entities. The manifestation of the will is the pursuit of perfection, because this is the goal of the existence of every spiritual being and depends on the role that a given spiritual being plays towards the Creator. Love is an externalization of emotionality, which determines the position towards God and towards all of the universe. Generally spiritual beings are varied depending on their position on the Original Being.
