"I wonder sometimes why climbers embrace climbing so ecstatically, with a passion that feels spiritual, even religious. For years, I never questioned this deep love. I simply realized that I had been looking for something for a long time and had somehow miraculously found it before I even knew it was missing. Now, when I consider the mainstream Western culture that produced me, I see there is something seriously missing for a lot of people. An altered experience of reality is fundamental to a spiritual worldview. Perhaps that is what climbers glimpse—sometimes in the mountains, sometimes when reaching deep within to push past physical limits. Many of us have never felt it before, and we will give anything to get closer to it in the only way we know how."
