Why did the oil lamp in front of the Buddha suddenly go out?

There are several reasons why the oil lamp in front of the Buddha suddenly goes out: one kind of wick is too short to cause the lamp to go out;

One is that the lamp is small and easy to be blown out by the wind, and the other is caused by insufficient lamp oil.

Pay attention to check your thinking and see what the reason is. It is common that the wind from opening and closing the door or walking may blow out the lights.
