Netflix adapted the Manga-style Death Note series to live action. Casting a young protagonist who receives an interactive spell book in which decrees are inscribed, naming each human victim, along with their prescribed cause of death. In the clip linked below, a fallen spirit named Ryuk also appears, who personifies an ancient death god type of creature—the spirit who orchestrates the killings.
The interaction between protagonist and spiritual entity clearly illustrates how witchcraft in general, and more specifically sorcery, operates. Where a human agent cooperates with a demon. As he inscribes a mark in the physical realm, which the fallen spirit then operates through. Demonstrating the expressions of spiritual authority and spiritual power. Sorcery in a nutshell.
As human beings operating in the world, we should soberly consider our choices in this esoteric dreamworld. Remaining fully aware of the fact that demons like Ryuk are actually hard task masters. In other words, there is a serious spiritual price to pay while dealing with powers of darkness, which can certainly lead to deeper, darker forms of occult ritual which may become more and more difficult to recover from.
