This is a simple practice to check in on your state of mind. Sit comfortably and rest your right or left hand on your lap or the arm of your chair. As you breathe in, close your hand gently. As you breathe out, open and relax your hand. You can start with one hand, then try with both hands, as your ability to maintain your awareness increases. Your hands are like flowers, opening and closing. Breathing in, make a very gentle fist, but don’t cause tension. Breathing out, just relax and let your hand open. See how many breaths you can follow and be aware of.
