For me, it's sitting in a bathtub with the shower running.
The gentle steam + the white noise of the droplets hitting the tub.
I travel a lot for work ... Almost every hotel (in North America) comes with a tub and shower. ... So, I can meditate almost everywhere I go.
Trust me, you do not want pictures.
"Trust me, you do not want pictures."
Well, maybe not me. But you never know who might :-)
