The Vision...

That is why Plato says of The One, “It can neither be spoken nor written about.”

If nevertheless we speak of it and write about it, we do so only to give direction, to urge towards that vision beyond discourse, to point out the road to one desirous of seeing.

Instruction goes only as far as showing the road and the direction.

To obtain the vision is solely the work of him who desires to obtain it.


Plotinus
Enneads, VI. 9. 4.
