There is a recurrent spiritual idea that there might be an organ of spiritual perception - an inner 'Third Eye' - by which we might see reality; see, in particular, spiritual phenomena imperceptible to the ordinary senses.
But this idea is conceptually incoherent; because any inner spiritual eye would be prone to the same problem as any ordinary eye; which is that the meaning of reality is not Out There, but requires our own thinking. To know The World therefore requires not merely perceptual information (what we see, hear, touch, taste or small) but instead the true conceptual understanding of perceptual information.
This 'combination' of perceptual and conceptual can happen in thinking, and only in thinking; and only when thinking is truth-full, real - is, in sum, the thinking of that aspect of each Man that is divine.
So, it does not matter whether an eye is one of the usual two organs that are located on our faces, or if it is an inner Third Eye - anything that is perceived by any means always requires to be interpreted and understood.
Seeing is Not believed, not even with an inner eye, because we do not comprehend the meaning of what we see unless we are able to interpret what we see in light of true concepts, true theories.
