The practice of leaving settled society to undertake a spiritual journey, or a spiritual life really, is something that is much more common in India. Common especially to a certain phase of life, to the end of life. But not so unusual for younger people as well.
Diana L. EckThe journey to sacred places is the most common way that people travel in India. They are always going on pilgrimages to sacred places. They are always undertaking spiritual journeys to visit the great shrines in the Himalayan tier of pilgrimage places; these places are called tirthas, a word that means "crossing place," a place where you can cross the river to the far shore but also cross over into another dimension of life. Cross over to heaven, in one sense it's used.
