I did a practice week at a temple in Thailand where we did a lot of walking meditation, up to eight hours a day.
We slept in a dorm on a concrete floor with only a thin mat.
We washed with collected rainwater which was a slightly brown.
Toilets had no flush. To flush, one had to scoop up water from the large rainwater tank with a bowl.
Day 4: Just before lights out Mek tells us that he couldn't sleep the night before because there was a cockroach. Too much information!
Day 5: The temple cat suddenly comes slowly pacing towards the walking meditation area of the newbies with something in her mouth. Turns out it's a little green snake, and she wants to play with it a bit. The three of us newbies are startled and stop, of course. I find a long stick and Mek - who is brave enough - gently picks the snake up and puts her on a path away from us.
Day 6: The temple dog shows up during the afternoon session and lies down on my walking track. Can totally understand, as my track is rather shady and the clay feels cool.
Every morning and evening we chanted in Pali and Thai. Then one monk would summarise what we had recited. Another monk would then preach (often up to one hour I think), followed by more admonitions by Venerable Grandfather. To summarise a typical sermon: "Worldly things are bad! bad! bad! Never leave your practice! Endure the pain! It's good that you are now here practising. Not like those lazy people everywhere who sit comfortably in a room with air condition. Did you know there's air condition in hell?"
