Answer: A soul is a certain space inside a human being in which one senses the upper world.
In an ordinary person living in this world, there isn’t a soul; there is only a point, an embryo, a drop of semen, from which develops the speaking level.
Question: Does a soul have a gender?
Answer: No. There are various modifications of the soul, but it doesn’t really matter. Each one of us has a soul. But at the same time, there is one common soul for everyone.
Question: How do we calculate the number of souls? Is it possible that is an excess of them?
Answer: What does “an excessive of souls” mean? The soul does not exist apart from a human being. If one develops it internally, then one has a soul. If not, one doesn’t have a soul. Each one of us is granted a chance to cultivate a soul and feel the next level of existence, the future world.
Question: What do souls do after death?
Answer: Souls do not die and have nothing to do with life or death of a physical body.
