The problem with feeling the spiritual world, meaning the total volume in which we exist today, is the problem of its perception. Now we are also inside this volume, along with our nature, which is still concealed from us. However, we feel only a small part of it with our earthly, bodily senses.
We have to attune ourselves so we would feel not only what enters our small egoistic desire. After all, it’s enough for egoism to desire something and we suddenly perceive what we did not notice earlier.
For example, when I start a new job, I start working with new materials and new phenomena, and some time later I start to feel what I am working with. We are attuning ourselves to a finer perception, creating inner models of phenomena and objects that we are dealing with. For example, a metalworker feels a metal by its sound and by the motion of the chisel. Likewise, people connected to nature understand it through signs that we are unfamiliar with.
We are created so that the surrounding world is depicted for us in a three-dimensional coordinate system. But is this really so? Other creatures perceive the world in a completely different way: through smells, temperature waves, ultrasound waves, and so on. However, no matter how much we expand the range of perception in this world, we always come across the same restriction: ourselves, our capability to receive or absorb inside.
In this way we limit our perception and do not feel the huge world that is around us. Gradually we begin coming closer to understanding these phenomena, or at least to the sensation that this is really so. However, it is difficult for us to cope with this and to work with this difficult problem because that is how our bodies are built.
Thus, as a result of our earthly development, it becomes clear to us that we are simply blind. We do not see where we are or how to live. This brings us to feel enormous suffering, which accumulates more and more. On one hand we develop, while on the other hand we do not know where and how, or what to do with ourselves.
As a result it becomes simply necessary for us to break down the barrier separating us from the real world. It is necessary for us to understand it because we cannot continue to exist this way. We already see that there is a certain psychological barrier here. Whether it is inside us or outside of us, we have to overcome it.
