I now walk into the wild. - Jon Krakauer

Early on a difficult climb, especially a difficult solo climb, you constantly feel the abyss pulling at your back. To resist takes a tremendous conscious effort; you don't dare let your guard down for an instant. The siren song of the void puts you on edge; it makes your movements tentative, clumsy, herky-jerky. But as the climb goes on, you grow accustomed to the exposure, you get used to rubbing shoulders with doom, you come to believe in the reliability of your hands and feet and head. You learn to trust your self-control. By and by your attention becomes so intensely focused that you no longer notice the raw knuckles, the cramping thighs, the strain of maintaining nonstop concentration. A trancelike state settles over your efforts; the climb becomes a clear-eyed dream. Hours slide by like minutes. The accumulated clutter of day-to-day existence — the lapses of conscience, the unpaid bills, the bungled opportunities, the dust under the couch, the inescapable prison of your genes — all of it is temporarily forgotten, crowded from your thoughts by an overpowering clarity of purpose and by the seriousness of the task at hand. At such moments something resembling happiness actually stirs in your chest, but it isn't the sort of emotion you want to lean on very hard. In solo climbing the whole enterprise is held together with little more than chutzpah, not the most reliable adhesive.

At that stage of my youth, death remained as abstract a concept as non-Euclidean geometry or marriage. I didn't yet appreciate its terrible finality or the havoc it could wreak on those who'd entrusted the deceased with their hearts. I was stirred by the dark mystery of mortality. I couldn't resist stealing up to the edge of doom and peering over the brink. The hint of what was concealed in those shadows terrified me, but I caught sight of something in the glimpse, some forbidden and elemental riddle that was no less compelling than the sweet, hidden petals of a woman's sex.
In my case - and, I believe, in the case of Chris McCandless - that was a very different thing from wanting to die.

But at times I wondered if I had not come a long way only to find that what I really sought was something I had left behind.
