Immediately when you arrive in Sahara, for the first or the tenth time, you notice the stillness. An incredible, absolute silence prevails outside the towns; and within, even in busy places like the markets, there is a hushed quality in the air, as if the quiet were a conscious force which, resenting the intrusion of sound, minimizes and disperses sound straightaway.

...Perhaps the logical question to ask at this point is: Why go? The answer is that when a man has been there and undergone the baptism of solitude he can't help himself. Once he has been under the spell of the vast luminous, silent country, no other place is quite strong enough for him, no other surroundings can provide the supremely satisfying sensation of existing in the midst of something that is absolute. He will go back, whatever the cost in time or money, for the absolute has no price.”
