It is said that a visitor once came to the home of Nobel Prize–winning physicist Niels Bohr and, having noticed a horseshoe hung above the entrance, asked incredulously if the professor believed horseshoes brought good luck. “No,” Bohr replied, “but I am told that they bring luck even to those who do not believe in them.”
for me, reviving some of the practices from my cultural community even though i don't believe in the symbolism nor religious adaptations to it anymore makes me feel like i have some sort of connection and it makes me happy.
it's also makes me momentary relive some of the happy memories of beloved people who have been gone for decades in a really efficient and celebratory manner that keeps any sort of sadness about it at a distance while keeping their memories alive.
