By walking naked you gain far more than coolness. You feel an unexpected sense of freedom from restraint. An uplifting and almost delirious sense of simplicity. In this new simplicity you soon find that you have become, in a new and surer sense, and integral part of the simple, complex world you are walking through. And then you are really walking.

It is always there, of course, when you come back from the green world. You have been living by sunrise and sunset, by wind and rain, surrounded by the ebb and flow of lives that respond only to such simple, rhythmic elements. But now the tone and tempo of the days switch. Instead of harmony, jangle.

Life should be an unfinished business.

I had better admit right away that walking can in the end become an addiction ... even in this final stage it remains a delectable madness, very good for sanity, and I recommend it with passion.

Under most conditions, the best roof for your bedroom is the sky. This commonsense arrangement saves weight, time, energy, and money.

Even in these mercifully emancipated decades, many people still seem quite seriously alarmed at the prospect of sleeping away from officially consecrated campsites, with no more equipment than they can carry on their backs. When pressed, they babble about snakes or bears or even, by God, bandits. But the real barrier, I'm sure, is the unknown.

Freed from the pressure of haste, the tyranny of film, and now the restraint of clothes, I found myself looking more closely at what went on around me.
