The Daoist solution to worry and bad thoughts, is “fasting in the heart” and “sitting in forgetfulness” 心齋坐忘，literally keeping all desires for anything or any goal out of the heart, and all images of any sort out of the mind. Though this is “easier said than done” in the western healing tradition, it is very much a part of the Daoist centering form of practice, and has deeply changed/influenced the coming of Zen and Samatta-vipassyana to China and the rest of Asia. All 3 methods are basically the same, ie, focusing all of the body and mind’s attention on the belly, or rather, the body’s actual (ie physical) center of gravity. That is why Zen, Tantric, and Daoist meditation all fold left hand (under) and right hand (over) each other, then press the 2 thumbs against the navel. The centering position is from 3 to five inches in, (depending on one’s weight) halfway between the 5th lumber vertebrae and the lower folded part of the hands. Athletes, artists, and Taiji/Bagua experts do this automatically; the rest of us learn it by watching the breathing process, ie, seeing air breathed into the lungs, circulated around the body, then exhaled, carrying with it any thoughts and desires we may have stored inside us. Or, put the thoughts and images into a rocket ship, and see them blasted off into outer space. Or, tie the mind like a “monkey” to the shore, and sail away in a boat. Then bring the mind and heart down into the belly, as if on an elevator; once in the belly, burn away all images, until nothing is left. I taught this over a 2 year period to people in the mental ward of Tripler Hospital, in Honolulu, Hawai’i, with good results; the nurses invited me back 2x – 3x a week. Another way to do this is to offer an “Agni-Hottra” fire ritual, write down all our good and bad deeds, good and bad images, on a piece of paper, and burn them. This can be done in reality by a real bonfire, and in our imagination after that.
The last, and perhaps best method to eliminate all unpleasant, demonic, and evil thoughts from our consciousness, is to place a sacred image between us and the evil image, person, or threat. For Tibetan Buddhists, Mahakali (Palden Lhamo) is the most powerful. For Daoists, Marishiten or Doumu (Mother of the Pole Star, who gives birth to thunder and lightning) is used. Best of all, however, for Christians as well as all people who have her image, is the Blessed Virgin Mary. Our Lady of Guadalupe is most effective, because the rays of the sun emanate from her, while she is pregnant with Baby Jesus.
