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.
There is the same difference in a person before and after he or she is in love as there is in an unlighted lamp and one that is burning. The lamp was there and it was a good lamp, but now it is shedding light too and that is its real function.
