Plotinos: Complete Works, v. 1 In Chronological Order,...

By making use of these mysterious figures, wise interpreters wished to indicate how the divinity might be seen. But the wise hierophant, penetrating the mystery, may, when he has arrived thither, enjoy the veritable vision of what is in the sanctuary. If he have not yet arrived thither, he can at least conceive the invisibility (for physical sight) of That which is in the sanctuary; he can conceive the source and principle of everything, and he recognizes it as the one particular principle worthy of the name. (But when he has succeeded in entering into the sanctuary) he sees the Principle, enters into communication with it, unites like to like, leaving aside no divine thing the soul is capable of acquiring.
