My mother-in-law is a Buddhist and has been burning incense for decades, but recently she seems to have been fooled and invested a lot of money.

Your mother-in-law believes in Buddhism, but she is not a true believer. If you want to convince her, you must understand Buddhism yourself. As for doing Buddhist services, we can persuade them from the aspect of cause and effect, and we can refer to three generations of karma sutra and abandoned under the temptation. As for fortune telling, you can tell her that the Buddha forbids disciples to tell fortune, and the Buddhist scriptures clearly stipulate it. Ananda asks Buddha for good or ill luck (excerpt): Mourning, moving and getting married are the world. Those who are interested in the world are disciples of the Buddha, and are not allowed to ask: please forbid, spell, hate strange things, worship in temples, and have fun, and are not allowed to choose good days and auspicious times. Fude people have received the five precepts of Buddhism and also done something, which should be three enlightenment; The mystery of Buddha's omniscience. Those who abstain from morality are strong in Tao protection and have no respect for dragons and ghosts! If you abstain from precious things, you should respect them. Bad luck, bad people have nothing to be afraid of! Tao covers the whole world, and those who fail to reach it hinder themselves. Good and evil are what people do, and good and evil are what people do, like shadows chasing after shapes and answering. The virtue of forbearance should be natural, protected by heaven, moved by ten parties, and integrated with heaven; The merits are boundless, and the saints sigh, which is difficult to weigh! A wise man has a destiny, has no body and no evil, is as good as Buddhism, and can live in the world. '
