Learning--the Everlasting Journey

I found "The Idea" by Mark Strand to be about one attempting to get out of where they were and getting to another place, obtaining knowledge and experience he/she didn't have. The poem starts with these lines: "For us, too, there was a wish to possess / Something beyond the world we knew, beyond ourselves, / Beyond our power to imagine..." (Strand 1-3). The "us" in the poem wanted to go beyond the world they know to possess something out there--to obtain more than what they have. The poem continues: "...something nevertheless / In which we might see ourselves; and this desire / Came always in passing, in waning light..." (Strand 3-5). By attaining another perspective, they would be able to look at themselves from that other perspective, being able to see what they haven't seen before, another side of them. Also, that desire they had came in vagueness. They may not have been sure about the emerging desire, being so dismal; and/or they may have been trying to hold it back--knowingly or incautiously. Although they finally find another place, they didn't step out of the liminal place and step in there:

And there appeared, with its windows glowing, small,
In the distance, in the frozen reaches, a cabin;
And we stood before it, amazed at its being there,
And would have gone forward and opened the door,
And stepped into the glow and warmed ourselves there,
But that it was ours by not being ours,
And should remain empty. That was the idea. (Strand 14-20)

Although the place looked much comforting and warm compared to the coldness they had came through, they decided not to go in there. They say that the "cabin" was theirs by not being theirs. Even though they don't own the place, they know it from their perspective. It was something in their perspective at that point since they are looking at it from the outside. However, if they enter the cabin, they have a whole new perspective, and even if they settle down after the bewilderment and come up with another stable perspective, it will be different from what they had before, and that perspective would not have been the one of the past them. What was the purpose of the idea? By stating that it shall remain empty by not going in there, however, they are saying that they had come all the way through the liminal space to not go where they had planned to. Are they afraid of going in there--afraid at what may be in there? They could find something completely different and new...but they could find the things that they know of. Are they afraid of finding out that the suffering they went through to get here was meaningless? Or, have they attained what they wanted from the traveling and therefore seek no more? Was the step in solving the one that was the most meaningful and not the results?
