Have two minutes?
While sitting comfortably, take a few slow deep breaths and quietly repeat to yourself “I am” as you breath in and “at peace” as you breath out. If distracting thoughts enter your mind, focus your attention on your breathing; inhaling and exhaling as you repeat “I am at peace”.
Have five minutes?
Set a timer. Sit quietly by yourself, and rest your hands loosely on your lap. Uncross your ankles, letting your legs comfortably fall apart and feel your body sink into the chair. Take slow, deep breaths in and out. Focus on the sound of your breathing. If other thoughts come into your mind, imagine that they are clouds and allow them to just float away. Relax. Just be in the present as you sit there and focus on your breathing.
Have fifteen minutes?
Start by taking some slow deep breaths, as you take a walk and look around at your surroundings and focus on what you see, hear and smell. If distracting thoughts enter your mind, bring your focus back to your walk as you continue to breathe.
