1.382

方等經云。不得祭祀鬼神。不得輕於鬼神。不得毀壞神廟。假使有人祭祀。亦不得輕於彼人。亦不得與彼往來（文多不載）。

The Vaipulya Sūtra states: 'One must not sacrifice to ghosts and spirits; one must not hold ghosts and spirits in contempt; one must not destroy shrines of spirits. Even if someone sacrifices, one must neither hold that person in contempt nor interact with him' (the text is lengthy and not recorded here).
