"In the desert I had found a freedom unattainable in civilization; a life unhampered by possessions, since everything that was not a necessity was an encumbrance. I had found, too, a comradeship inherent in the circumstances, and the belief that tranquillity was to be found there. I had learnt the satisfaction which comes from hardship and the pleasure which derives from abstinence: the contentment of a full belly; the richness of meat; the taste of clean water; the ecstasy of surrender when the craving for sleep becomes a torment; the warmth of a fire in the chill of dawn."
