Try this: bring yourself into the present moment, tune out all that’s going on around you, and feel peace now. Just feel totally calm and at peace. Now, intensify that feeling. Let it flow all through your body like honey. Notice how it makes you feel. Especially tune into the feelings in your hands: are they tingling?
Now, make the feeling even stronger, burning through your body like a brilliant white light. Do you feel it? Just sit a moment enjoying the feeling, bathing in the brilliance. Now, use your hands to compress the light into a small, radiant ball of luminosity, and slowly move it into your solar plexus. Breathe deeply as you do so. Is it firmly in place? Good. Now, keep it there for the rest of the day, checking in with it from time to time to get both energy and calm. If anything today starts to bother you, think immediately of your luminous ball of peace that is now part of you, and feed the annoyance there, where it will quickly burn to a light ash and blow away. Do this just for the entire day. When you go to bed tonight, lift the light and let it float over your body as you go to sleep.
Let me know how it works for you!
