Practice in a comfortable position, sitting on a cushion, chair or meditation bench and make sure your spine is straight. Rest your hands in whatever position you like. Once you have found a comfortable position, make an intention to stay in that position for the whole meditation without shifting or moving. The eyes can be open or closed. If they are too open you may become distracted, and if fully closed your meditation may become foggy or dull. So adjust your practice accordingly so that your meditation is vivid and lucid.
