Please ask the Bodhisattva to bless the elderly to recover soon.
It depends on whether you believe in Buddhism or Taoism. If you believe in Buddhism, you will read the Heart Sutra. If you believe, you can say the holy name three times. The full text is as follows: South China has no great compassion and desires, and it is harmonious and comfortable. There is no Guanyin in the south, and it is smart and comfortable. There are no thousands of hands and eyes in the south, and they are free from Buddha. There is no magic in the south, and avalokitesvara bodhisattvas are everywhere. There is no Guanyin in the southern purple bamboo forest, and it is smart and comfortable. There is no Guanyin in Nanchao Cave, so it is flexible and comfortable. The south has no sound to save the bitter Guanyin, which is flexible and free. Wu Nan has no idea of loving Guanyin. He is very comfortable with the Buddha.
