Why is our life so irrational? The answer is pretty simple. There are many systems in the universe that exist, function, develop and perfect themselves without our intervention. For example, now I see something and within me all sorts of processes are taking place, various wisely built systems are at work. I’m not even aware of them; they are not accessible to my comprehension; we cannot investigate, trigger them ourselves, control or govern them. The body lives.
Similarly, there have to be multiple systems outside and inside of a human being that would function both in human and spiritual aspects. They have to be inaccessible to a person and he should not deal with them. He has to work, be a head of a family and take care of various things. Thanks to this, he also undergoes correction, without knowing how.
