Try this: Sit in a relaxing posture. As you inhale, think "1". Exhale and think "2". Inhale and think "3" and so on up to "10". Then start over. In the beginning you will often end up counting 11, 12, 13, 14 and then realize you counted to far. Just start over with inhaling and counting "1" and so on. In my experience, after 30-45 minutes, the mind and body will come to rest in a profound manner. For details check out "Mediation for dummies", this is where I leared the technique. Best of luck.
