This content is about death transit which is the shift to the psychic world with no recourse of a physical presence. Generally human beings service a religion by consigning a dead body to a religious ceremony which promotes the idea of life hereafter in the heaven of a deity. However, the same survivors who sponsor the ceremony usually mourn the physical condition of the person's immobile body.
The religious overcoating is more or less, a sham. On this side of existence, the survivors take comfort in the idea that the person shifted to a heavenly world and is better off for it, but these people rarely have mystic perception to verify this idea.
The content of this literature is a broad declaration that what occurs at death of a body is not surprising. In fact, most everything will continue as usual on the physical and astral sides of existence. The world will go on. The psychic existence will continue. The cosmos will not blink for it.
