angel:  is other dimensional intelligent being; can only communicate with this dimension, but not physically alter anything, unless given special option from Divinity [if devil -- fallen angel -- could not physically interfer with any earthly choices, since then earthly beings would no longer have free will: barred by God and evolutionary logic; "possessions" of beings simply cases of devil occupying space as with a rock, but "rock" (being) willingly forfeiting all responsibility for their own personage].
