Reminds me of another Egyptian chart they used to visualize when attempting to vibrate their pineal glandes.

I think this one has to do with resurrection, summoning the corpse chakra from the aether; and gathering the sol(spirit) of those cores from the ionosphere.

The highlighted part on top left i think is meant for the ionosphere visualization and the part on the bottom right for the aetheral summoning.

Wonder what happens when I start meditating on this chart, last one helped me tap into my crown chakra.
