The Emmaus Road

Have read (well, skipped!, must delve deeper) Salley Vickers', The Other Side of You, in preparation for a sermon. An interesting article by her, also relating to the Emmaus Road of Luke 24 (and Eliot's The Wasteland) here:

If we take her insights to a higher key (they actually did see the Lord), what insights does this gives into this key passage in Luke?

(by Robert Cotner) we can learn how Eliot referred in The Waste Land to Shackleton (on whom I did something of a project some years ago). I quote from the site (but the whole article is worth reading):

"The link between poetry and exploration came full circle for Shackleton in the year of his death, 1922, of a heart attack in South Georgia as he was about to begin another trip to Antarctica. T. S. Eliot, in "The Waste Land," a poem which many consider to be the hallmark poem of that era, wrote:


Who is the third who walks always beside you?
When I count, there are only you and I together
But when I look ahead up the white road
There is always another one walking beside you
Gliding wrapt in a brown mantle, hooded
I do not know whether a man or a woman
—But who is that on the other side of you?


Eliot’s footnotes attributed this passage to Shackleton’s South (1920), in which, as Eliot wrote, "at the extremity of their strength, [they] had the constant delusion that there was one more member than could actually be counted." This "Fourth Person," as it came to be called in Shackleton’s writings, was the conscious presence of another being among the three explorers as they hiked the uncharted, never-before-traveled winter mountains in gale-force winds and knee-deep snows of South Georgia, on the last leg of the journey to save their marooned colleagues. This mystical experience, Shackleton wrote, must always be a part of the "record of our journeys."
By virtue of his unstinting love of his fellow men, Shackleton repeatedly gave up his dreams and risked his life to insure their safety and well-being. As an explorer, it seems to me, we should call him intrepid; as a leader, undaunted, as a person, perhaps, St. Ernest."


Can this give us insight into the book of Hebrews as well?
