How do we sit comfortably during a meditation?
While I don't meditate regularly I was shown a sitting posture that was very comfortable for me the few times I've tried it. I believe they called it "Burmese" style sitting. You sit in a half-lotus (or cross legged) position with cushions under your butt with your knees touching the floor. I use two thick kitchen chair cushions. The points of contact with the ground are the butt (on top of the cushions of course) and the knees. I've found sitting like this keeps my spine nice and straight like sitting in seiza, which is good because I can't sit seiza for long periods due to a knee injury
Hope all that makes sense
