The song, "A Thousand Miles", means a great deal to me. Let me explain what it means. The point of this lyric is to emphasize the illusory nature of the senses and highlight the inner world of experience and how it trumps the former. For, just as St. Peter had expressed right before he was crucified upside, he explained that the world was upside down. Obviously not the physical globe that floats about in space, but rather all that is captured by the senses. It's as if the epistemic faculties of Man were flipped, and all that is right is wrong, all that is good is evil, all that is up is down and all that is to the right is to the left. Our understanding of Space, Physics, Science is all moot; nay is certainly inadequate to capture all that there is to experience; one may as well try to scoop up the entire ocean with a serving bowl. And so, the action of falling into the sky is nothing more than falling into our graves, where the heavens are the ground and the greater outer space is nothing more than the dirt and soil of reality.
