Hades is not Saturn. Hades is the god of the underworld, Pluto. Hades is also the name of the underworld/afterlife. Tartarus is a realm of punishment for the truly evil, it is not Pluto nor any god at all.
I was comparing the model from a different angle.
Saturn=MULADHARA the code word for "hell" but which can also be a plane of existence for one in which the consciousness has not completely merged with the mind of the past life.
Tartarus can have several interpretations, not just this one.
Don't limit the visions because they are diverse, all these words are used for anything and everything of a specific nature.
Tartarus can also be a multi-headed monstrosity (someone will face this monstrosity when they die and have no salvation) but also simply an icy, wet, sticking Abyss
I can categorize this into levels of consciousness as well 7ceu-active consciousness
Tartarus=level of consciousness almost nil and still declining
There are various interpretations for countless things, we can safely assimilate one into the other as well.
