Magic is simply when someone uses an unseen, non-physical energy to work on another energy or vibration. It is very subtle. It can have physical effects, but it is not physical in itself. For example, falling in love may have physical effects, like making someone lose weight, produce more hormones, have erections or whatever. But this is not the result of something solid and physical acting on something else that is solid and physical: it is the result of energy, or the non-physical, acting on the spirit, which is also non-physical, which leads to changes in the body, which is physical.
