Then you can recite the Buddha and the scriptures. Of course, the power of this varies from person to person. Really sincere, it will change soon, because chanting Buddha and scriptures is to stimulate positive energy in the body. When positive energy comes out, it will break evil spirits. If you want to get out of this positive energy, it depends on your sincerity, your heart to stop evil and do good, and you must really believe it. Therefore, in a family, an old lady who is a Buddhist can save the family from disaster, because she really believes that she can be kind, and the positive energy inspired is infinite.
Of course, many old ladies believe in Buddhism but don't understand it, and often do superstitious behaviors. Buddhism is regarded as superstition in the eyes of the world. In fact, many old ladies don't understand the profound truth of Buddhism, but superstition is better than unbelief. Buddhism is actually related to all aspects of life. What is better now is that the profound truth of Buddhism can be found on the Internet.
