The only other instance of “mind’s eye” in philosophical or religious literature that I know of is the third eye in Hinduism, which is one of the chakras or energy centers in the body.
Many deities, like Kali and Shiva, and sometimes the Buddha, are depicted with their third eye open. He closest thing to a scientific theory of it is that the inner core of our brain is reptilian, and that because our earliest ancestors were cold blooded they needed to be in tune with the circadian rhythms, so this third eye helped to perceive the circadian rhythms. But the eyes are there for that, they see the light of the sun and report it to the brain...
So this idea is very pre-scientific and spurious...
