Neighbors worship idols on the balcony, with candles inserted, and the back of the idols is facing my bedroom window. What's the impact? How to avoid it? It's not going well recently.

In fact, most of the statues are extroverted, such as Sakyamuni Buddha in the Hall of Ursa Major. I guess your neighbor is an amateur.

To use an inappropriate metaphor (I hope God will not blame it), a good man protects three villages and a good dog protects three neighbors. God will protect you too.
