That’s interesting because one skilled magician on here, I observed he developed a new chakra in his chest, I’ve also seen different energy centres on people when doing healing, and the “new” ze’al chakra is also getting attention.
It’s my experience that the system most people know, the 7 wheel-like structures, is a formalised depiction of genuinely-existing energy channels BUT that they are neither rainbow-coloured, though that system does harmonise with their energy, nor all in the same location for everyone.
Just because there is no mention of a thing in the human body prior to a date doesn’t mean it was created then, people didn’t understand most phsyical organs and their role and mechanism until relatively recently, and continue to discover how things work on the cellular and genetic level even now.
Removing the constraints to energy they may represent is another topic, and whether they’re part of a slave system; it’s certainly suggestive of something like that, that altering chakras was the first thing I was given from the Ahrimanic current (The venom of Azi Dahaka).
