So I sit in a chair and sing quietly a dharani (spiritual song) inside myself and tap my thumbs against my index fingers to the rhythm and move my toes up and down to the rhythm and breathe in and breathe out to the rhythm and open my eyes and close my eyes to the rhythm and close my mouth when I breathe in and open my mouth when I breathe out to the rhythm and put my tongue behind my front teeth when I breathe in and put my tongue behind my lower teeth when I breathe out and gradually slow it down and I know that it's difficult but give it a try and see what you think.
