Each of the world's indigenous cultures carry their own versions of the 'vision quest'. At the baseline, vision quests are whatever ritual brings new vision and restores perspective to your life. Often times this experience is powerfully transformative and initiatic; the vision quest changes your life. Typically people go on vision quests when they have lost perspective and need a vision to live by or live for. Though many ritual traditions define vision quest as a social or group event, there is usually an extended period of solitude involved. Each vision quest tradition also has its own specific preparations, diet-wise and otherwise, that participants adhere to before embarking on their journey. There is obviously much more to the vision quest. Hopefully these words can give you some basic ideas and guidelines.
