Isnt it a Buddhist belief that there exiet so called Demons

[catmoon]

How does karma work in relation to so called Demons, Are they subject to it? And what does Buddhism say on how do Demons operate?

The dogma of various sects is rife with supernatural beings of all kinds. Never having been affected by any of them, I tend to ignore the lot. I have to deal with seven versions of Buddha in Medicine Buddha practice and that's plenty for me.
