The Spirit
Since the Spiritual Realm floats at the highest point of all other above-mentioned worlds the spirit stands also in the highest place among other inhabitants of the worlds. Indeed what do the spirits look like? The entities generally called spirits seen or felt by some sensitive men are the souls in fact and not the spirits. Man can only see with his ethereal eye into the astral world which is a medium part of gross matter. More developed men "see" as far as ethereal matter. In the dreams man can perceive souls of both living and dead people. The soul comes out of the body during the sleep and wanders through immense distance. Man need not to be afraid of its not coming back since the soul is connected with the body by an astral line which is of "infinite" length.
The Law of the Attraction of Homogeneous Species hinders man to see a spirit or the Spiritual World. There is too far away from the universe to the Spiritual Realm. The spirit is of finer substance than the soul because unlike the soul it is immaterial. However, it looks alike, it is a man or a woman but of much more beautiful, blazing and perfect appearance than men or souls have. One already knows that the soul is ethereal and therefore, it is more durable than gross matter, the body but it will also perish sometime. The spirit will not perish; it is eternal since it is immaterial.
