One stick worships gods, one sticks to drive away evil spirits, and one stick bury people - and this time, no one can escape when the incense burns out.
Three sticks of incense are about to burn out:
A stick to worship God? God has become a demon.
A stick to drive away evil spirits? Evil is human desire.
Burying someone with a stick? When the incense burns out, no one can bury it and no one can escape.
