A pilgrimage is a journey, often into an unknown or foreign place, where a person goes in search of new or expanded meaning about their self, others, nature, or a higher good, through the experience. It can lead to a personal transformation, after which the pilgrim returns to their daily life.
Typically, it is a journey to a shrine or other location of importance to a person's beliefs and faith, although sometimes it can be a metaphorical journey into someone's own beliefs.
Many religions attach spiritual importance to particular places like the place of birth or death of founders or saints, or to the place of their "calling" or spiritual awakening, or of their connection with the divine, to locations where miracles were performed or witnessed, or locations where a deity is said to live or be "housed", or any site that is seen to have special spiritual powers. Such sites may be commemorated with shrines or temples that devotees are encouraged to visit for their own spiritual benefit: to be healed or have questions answered or to achieve some other spiritual benefit.
A person who makes such a journey is called a pilgrim. As a common human experience, pilgrimage has been proposed as a Jungian archetype by Wallace Clift and Jean Dalby Clift.
