Prayer obtains what it is due to obtain — not what I personally want to obtain, which is different. It is useful that islands of prayer exist in the world, even if they are composed of only one person, or two, or three, or four.
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.
