There is an art to wandering. If I have a destination, a plan -- an objective -- I've lost the ability to find serendipity. I've become too focused, too single-minded. I am on a quest, not a ramble. I search for the Holy Grail of particularity and miss the Chalice freely offered, filled full and overflowing.
A legend told by the Venerable Bede says that the poet Caedmon was once completely mute. It was a custom in his village to spend evenings taking turns reciting poetry. On these occasions, Caedmon, unable to speak, would steal away to nearby hills to escape. One evening while walking alone, an angel appeared and urged him to sing. Miraculously, he began to sing and went on the become a famous poet.
