On the subject of cushions, my tactic was simple.. I stopped using one, thereby starting the process of getting my body used to a flat surface to sit on, so that I may comfortably park my behind on any piece of ground I should happen to come across and feel inclined to install myself on.
Just for once (don't get excited, I won't let it happen agin
) I'm going to have to agree with you on this point. Cushions are necessary though until the hips and knees get used to lying down flat. It is not so easy for westerners used to sitting on chairs all their lives.
Agreed here too. Except when my back hurts, then I need a little support.
Something I often suggest is to sit on a large phone book and every day remove one page until you are able to sit on the floor.
If the phone book has 300 pages in it, it should take less than a year.
