The Vietnamese word "hương đăng" is an old term that means "to worship" or "to offer incense and light" in a religious or spiritual context. It is often used in ceremonies and rituals, especially in Buddhism and ancestor worship, where people light incense and candles as a way to pay respect and honor deities or ancestors.
While "hương đăng" primarily refers to the act of worship through lighting incense, it can also metaphorically relate to the idea of seeking guidance or enlightenment in life.
