The Fellowship of the Ring by J.R.R Tolkien (Harper Collins 1991) pp. 391-392
It all begins because Frodo has to flee from Boromir wearing the Ring in order to do so. Frodo climbs up the slopes of Amon Hen and finally reaches its top.
“He saw as through a mist a wide flat circle, paved with mighty flags, and surrounded with a crumbling battlement: and in the middle, set upon four carven pillars, was a high seat, reached by a stair of many steps.”

The high seat upon Amon Hen has always been a place set apart for reflection, an expression of the belief that if only we can get high enough, if only we can somehow rise above all the chaos that surrounds us, we will achieve a kind of clarity and will know what we must do. But in all the long years since first the seat was placed upon this hill top by the men of Númenor there has never been a moment like this. No-one has been able to see as Frodo does because no-one has sat upon the chair while wearing the Ring.
And what Frodo sees is war. “The Misty Mountains were crawling like anthills; orcs were issuing out of a thousand holes. Under the boughs of Mirkwood there was deadly strife of Elves and Men and fell beasts. The land of the Beornings was aflame; a cloud was over Moria; smoke rose on the borders of Lórien.”
And last of all, and perhaps inevitably, Frodo’s gaze is drawn towards the place in which the Ring was forged and the tower in which its master dwells: “wall upon wall, battlement upon battlement, black, immeasurably strong, mountain of iron, gate of steel, tower of adamant, he saw it: Barad-dûr, Fortress of Sauron. All hope left him.”

It is at this moment that Frodo becomes aware that someone is searching eagerly, voraciously, for him, for the Ring that he is now wearing; and that this creature, whose very being has become an embodiment of desire, so entire, that if the thing that he longs for were to cease to exist there would be nothing left of him but a memory of what he once was, will find him. And it is at this moment too that he becomes strangely aware of a familiar voice telling him to take off the Ring.
“Take it off! Take it off! Fool, take it off! Take off the Ring!
The struggle lasts only for a moment but during that time the whole fate of Middle-earth lies, literally, in the balance. Frodo is held, “perfectly balanced” between the Voice and the Eye. If Sauron is able to find him, to identify exactly where he is, then he will regain the Ring at last and darkness will fall.
Crucially, this moment is resolved when Frodo becomes “aware of himself again” as one who is free to choose and he takes off the Ring. “Then all the sky was clean and blue and birds sang in every tree.”
Frodo is not only able to think for himself again but he is able to achieve a clarity of purpose that all his seeing could never give him. Not that the vision that he has been given upon Amon Hen has been of no value for it has enabled him to see that he cannot put his trust in any power outside of himself because every power is as nothing compared to the power that resides within Barad-dûr. All that he has is the Self who is able to make this choice, the choice to go alone to Mordor.
The problem with hope is, as T.S Eliot puts it in his Four Quartets, is that “hope would be hope for the wrong thing.” There is no hope for Frodo in Minas Tirith because, for all its courageous beauty, it cannot stand at the last before the power that is rising against it. All that he has is himself and the choice that he made at the Council of Elrond to take the Ring to the Fire though he did not know the way. As Eliot puts it, following his teacher, St John of the Cross, we come to the point in which all hope has been stripped away and there we find, as Frodo does, that “the darkness shall be the light, and the stillness the dancing”.
