What I could use now is a good dirty joke ... or even a good clean one.
Having spent the morning between 5 and 1130 working on a bureaucratic form -- make sure of spelling, commas, tone, facts etc. -- I feel as if there were sludge in my thinking department.
Jokes are high-octane, on-target, blackboard-erasers.
Funny how laughter or sneezing or any number of other things just seem to clear things up and put you on track.
Zazen ain't bad either.
