In the "Sleeping legs" thread Jundo mentioned the opportunity of alternative sitting - Insta-Zazen(also poissible of course as a compliment to a daily sitting). Has anyone tried that?
I don't have the opportunity to actually be alone say on the commuter train but I have plenty of time and this too is a chance. I wonder if you guys have some tips. The back part of the seat on a train is impossible to bring into the perfectly vertical position but leaning onto it would make me drowsy in an instant. Also, there are more distactions than at home, etc. May be not zazen proper but something close to help one better the concentration?
