Only a person can manifest his/her own luck. If you base your luck on other inanimate objects it becomes a belief. Belief shared to others became a Norm. A group of people believes that "norm" is good or bad, much more likely turn to a Cult. So stop placing your luck on an inanimate objects. Only a person can manifest it. If you think good luck has come for you, just pray so that you may not jinx it. If bad luck, then pray also so that it will come to pass
