Lacking What They Have
Lean into this (as you may be projecting these beliefs onto your twin):
Does this pattern of thinking remind you of anytime you were compared or didn't measure up?
ie. this could something from your parents, or teachers, or coaches. this could be witnessing comments about what is special about someone, never hearing that about yourself.
What to do with it now?
Acknowledge it, release any ownership over that belief and establish your own beliefs about unconditional love. Being aware of where this pattern came from will help you to establish that you most likely took on someone else's version of the truth.
You were and are now worthy of the most beautiful love, as you are in this moment.
What if I told you that this particular karmic person is exactly how they are to help you acknowledge where you feel insecure about yourself. Do any of the things they have that you don't hold true value? Are they physical, superficial, society's standard of special? Chances are they are coming up so you can reconcile the truth about the fact that you do measure up, and there is nothing lacking about you.
