"Wanderer" is a symbol of a man whose life is like a short time on earth.
The "wanderer" is also a symbol of a righteous man who has a worldview that corresponds to the Will of God, and therefore is aware of the frailty, the temporality of his physical sojourn in the body. It is a person who perceives material, earthly life as a short journey to the eternal "Abode" prepared by God for all the righteous - to Eternal Life, life beyond matter, time and space.
