I looked at the O.P. reference.

The pic at the bottom.

Teonanácatl was the means of transport to divine realms.

Meaning.... psilocybin mushrooms.

If you look at the pics you'll see the stalks on some of them.

Those are depictions of mushrooms.

The humanoid figure is, "in," a mushroom, stalk and all, coming forth from yet another beneath it.

Those who have really spent the time and effort to get to well know this mushroom, and that includes spending time alone in the dark quiet, know the cosmic ramifications.

And the, "visitors," that can literally come on down... sometimes scaring neighbors to pull up stakes and move...
