During the Holidays we are most often found indoors escaping the cold and darkest days of the year. Holiday decorations, Christmas music, invitations to go here and there plus a list of things to do can unbalance us and make us jittery. My suggestion is to ground and center yourself by going outside no matter what the weather is and sit still. Notice and maybe even journal what you see, hear, smell and feel. When you're done take 3 deep breaths and go on with your day.
Before you go to bed at night be sure to revisit where your mind was during your outdoor meditation by sitting in silence for a few moments and/or read what you wrote in your journal. See if any of the qualities you noticed of the coming winter stayed with you as you moved through your day.
