Jealousy Has a Boomerang Effect
A jealous thought about someone does little to the person you’re thinking about. To the contrary, the thought simply bounces off that person, and comes back to you. Let’s say you’re thinking about how someone you know has more money than you, and perhaps you believe that they don’t really deserve it because you work a lot harder than them. The Universe then reflects that thought back to you and simply reinforces your core belief, which in this case, is something along the lines of “there is injustice in the world, and people are succeeding unfairly.” It doesn’t matter if the thought is actually true. If it reinforces a negative core belief you hold, it is ultimately detrimental to your manifestation efforts.
