Wishing bad things harms

If someone harms you on purpose, don't wish them bad.

Why?

Because according to the Law of Compensation (also called Law of Exchange or Boomerang Effect), all that we emit comes back to us, you would therefore harm yourself because of that person who already harmed you.

Instead, wish them consciousness because this person will the have to face themselves, their actions and the consequences of these actions, and their karma, and they'll have to live with it. Karma is a Universal Law of cause and effect, like a scale that is balanced or imbalanced according to the nature of our actions and nobody can escape karma.
