Grandmaster JinBodhi: You can look elsewhere. But since Energy Bagua is a type of meditation practice, the longer you look at the tree, the better the results will be. When you fully concentrate on your practice, you benefit the most. You can read news, watch TV or even listen to ghost stories while practicing; your body will still heal itself, but the results will not be as good as if you concentrate.
Try playing the Energy Bagua music or the demonstration videos, as they help practitioners tune their minds into the practice state. As you circle, you can watch the demonstration video for a short while from time to time. That way, you will get even better results from practicing.
