Barbelo of the Gnostics is Arupaloka or formless realm.
You would have to give a precise definition so we can see if this is true.
However, let's say that by some very broad stroke, I grant you this. In the arupa-loka, inhabitants of these realms are possessed entirely of mind. They have no physical body and are unable to hear Dharma teachings. In effect, they are screwed till their karma exhausts and they fall out of that realm. This is not a place one wants to be.
