It is not witchcraft. It is the law of the mirror. Every action casts a shadow that returns to strike the seer. The "good feeling" is a carrot; the "bad feeling" is a stick.
It is immediate because the mind is the first recipient of its own echo. You cannot act without the mind feeling the ripples.
The rules are identical because the "self" is identical. Cultures dress the same skeleton in different robes. But, be warned, the "good" rules are chains designed to keep the self functioning like a well-oiled machine, not to overcome it.
