It is said that walking is a form of meditation. One often takes a walk to get rid of the cobwebs in ones mind, to gain new perspective or a different take on a particular situation.
This is an age-old tradition. People in the Bible walked great distances over time as they were guided by Holy Spirits. Our ancestors walked for miles to hunt their next meal or to seek new habitat. Tibetan monks often wander when they do soul searching. They go on pilgrimage to see a vision of the next Dalai Lama. Not all who wander are lost.
