I was jealous. Later, I will go out to the zendo and do a bit of zazen. The zendo is not air conditioned and I am too old to be much impressed with those who did or do their Zen practice through all sorts of extreme heat and cold.
If testing the harsh realities of climate or posture or mind were sine qua non's of spiritual endeavor, how could anyone expect to make a bit of progress? I can enunciate the spiffy answers and demurrers, but the best I can come up with is the old encouragement:
The hard stuff is easy. It's the easy stuff that's hard.
