Projections are like an infinity mirror effect of our shadows. It is unhealthy when project on/from another, forgetting that it is the other’s situation and that they have their own issues to deal with and their lessons are not ours.
We have been through lifetimes of different roles, picking up different virtues, unlocking different levels of achievements. There are times when we did not “pass the test”, but moved on to learn other lessons. We get to revisit “the test” as events that pop up in our lives.
Do you know that emotions and trauma can be passed down from our ancestors to us via DNA? Those we hate/resent/begrudge/fear/envy may well share the same bloodline that flows through us, or be the enemies they had to defend/fight against.
