It is true that Buddha discouraged people to indulge in these practices as many are just superstitions and deceitful. Even though some may be based on reliable studies and statistics, our future should not be bound by these fortune telling. Buddha teaches us that all things and phenomena in our lives are governed by the ‘Law of Cause and Effect’. Nothing that we encounter is haphazard as there must be a hidden cause we created in the past, i.e. everything whether good or adverse is self created. Based on this genuine truth, we are able to control our own fate and destiny as good begets good and bad begets bad. Buddha’s teaching is to tell us how to create our own better future and how to face adversity due to our past unwholesome deeds. Buddhism is a teaching that guides people to have a positive attitude towards life instead of relying on prophesy and fortune telling.
However, practices of fortune telling, fung-sui and so on have long been a kind of tradition and culture among the Chinese community for thousands of years and many people who are deluded about the truth of life, are still attached to them. Their practice has nothing to do with Buddhism. Though you may find such practices in some temples, these temples may not be Buddhist temples as many Chinese temples are devoted to the worship of deities and spirits. Even so if you find this in Buddhist temples, this is only a way to accord with people’s traditional beliefs, but still if they practice it, the effect mainly relies on their ultimate sincerity of the mind and not on superstitious belief.
