It's a sky based memory palace passed along through oral tradition. In order to ensure each realm of the palace is unique and individual they must be archetypal representations, putting as much distance in concepts between each other as possible. Given that these are humans creating these palaces they're going to project the sensory experiences they have available that fit those criteria. Nowadays they're called associations. That's going to include things like incense for smell, ritual food sacrifices for taste, and most importantly emotional connections and experiences that frame their understanding about the world. Chakras and the Tree of Life are body based Memory Palaces, working the same way.

The point is to remember that as the skies above us are determinate as a clockwork function of the universe, so are we living below.
