The Caravan of Summer
Something of the real difference between pilgrim and tourist can be detected by comparing their effects on the places they visit. Changes in a place—a city, a shrine, a forest—may be subtle, but at least they can be observed. The state of the soul may be a matter of conjecture, but perhaps we can say something about the state of the social.
Pilgrimage sites like Mecca may serve as great bazaars for trade and they may even serve as centers of production (like the silk industry of Benares), but their primary “product” is baraka or mana. These words (one Arabic, one Polynesian) are usually translated as “blessing,” but they also carry a freight of other meanings.
