Why can black dogs ward off evil spirits?
First, dogs are animals of the sun, and the twelve branches and five elements corresponding to dogs are the earth and the sun. Therefore, the boy black dog is born with the purest yang, and the yang controls the yin. Since ancient times, Taoist priests have used black dog blood to exorcise evil spirits and treat diseases.
Second, according to legend, the wheezing dog under Yang Erlang's seat is a black dog, which contains the spirit from nature to yang. The black dog on the earth is its close relative, so the blood of the black dog is a bit domineering. If there is no devil who has practiced for thousands of years, he can't get close.
Thirdly, once upon a time, a family kept a black dog. One day, the child at home was ill, and the black dog lay on the roof for a whole day without any reason. The family thought that the child was sick because the black dog was on the roof, so they killed the dog. As a result, the black dog died and the child died with him. Later, it was said that the child turned out to be a literary star and the black dog was spiritual. He went up to the roof and pinned down Wang Lingtai, the star of the next world, so that heaven could not find him. Since then, when Taoist priests cast spells to exorcise evil spirits, they used a knife to take dog blood from the hind legs of black dogs to increase their efficacy.
The above legends, whether true or not, were discovered by some masters who have practiced for many years. It is said that black dog blood does have the effect of exorcism. If you often have a ghost bed, you can apply the blood of a black dog to your eyebrows. If the situation is serious, you can dip your brush in the blood of the black dog and draw a circle under the edge of the bed to ward off evil spirits.
Taking black dog's blood, although it doesn't kill the dog, it will also hurt the puppy's body. The so-called equality of all beings, from the Buddhist point of view, is to kill life, but also give birth to evil obstacles. As a last resort, this method should not be used to exorcise evil spirits.
