“To lose a passport was the least of one’s worries. To lose a notebook was a catastrophe”

“We shall not lie on our backs at the Red Castle and watch the vultures wheeling over the valley where they killed the grandson of Genghiz. We will not read Babur's memoirs in his garden at Istalif and see the blind man smelling his way around the rose bushes. Or sit in the Peace of Islam with the beggars of Gazar Gagh. We will not stand on the Buddha's head at Bamiyan, upright in his niche like a whale in a dry-dock. We will not sleep in the nomad tent, or scale the Minaret of Jam. And we shall lose the tastes - the hot, coarse, bitter bread; the green tea flavoured with cardamoms; the grapes we cooled in the snow-melt; and the nuts and dried mulberries we munched for altitude sickness. Nor shall we get back the smell of the beanfields, the sweet, resinous smell of deodar wood burning, or the whiff of a snow leopard at 14,000 feet.”

“I climbed a path and from the top looked up-stream towards Chile. I could see the river, glinting and sliding through the bone-white cliffs with strips of emerald cultivation either side. Away from the cliffs was the desert. There was no sound but the wind, whirring through thorns and whistling through dead grass, and no other sign of life but a hawk, and a black beetle easing over white stones.”

“The real home of man is not his house but the road. Life itself is a travel that has to be done by foot.”

“The usual run of children's books left me cold, and at the age of six I decided to write a book of my own. I managed the first line, 'I am a swallow.' Then I looked up and asked, 'How do you spell telephone wires?”

“I never liked Jules Verne, believing that the real was always more fantastic than the fantastical.”

“Gradually the idea for a book began to take shape. It was to be a wildly ambitious and intolerant work, a kind of 'Anatomy of Restlessness' that would enlarge on Pascal's dictum about the man sitting quietly in a room. The argument, roughly, was as follows: that in becoming human, man had acquired, together with his straight legs and striding walk, a migratory 'drive' or instinct to walk long distances through the seasons; that this 'drive' was inseparable from his central nervous system; and, that, when warped in conditions of settlement, it found outlets in violence, greed, status-seeking or a mania for the new. This would explain why mobile societies such as the gypsies were egalitarian, thing-free and resistant to change; also why, to re-establish the harmony of the First State, all the great teachers - Buddha, Lao-tse, St Francis - had set the perpetual pilgrimage at the heart of their message and told their disciples, literally, to follow The Way.”
