The Jealous cause their own demise.
If you’ve had an insanely jealous partner, you know what I’m talking about. The jealousy comes from a fear of losing the love of that partner. What’s ironic, though, is that the jealousy (which has lack of self-esteem at its roots) is what ultimately causes the exact loss that jealous person most fears. This loss (because of the jealousy) serves to reinforce the jealous person’s world view, causing them to act even more jealous in the next relationship they manage to get in.
This concept of causing our own demise applies in other areas of life. Limiting beliefs and clung-to world views inherently cause reinforcement of those beliefs and world views. We tell ourselves and others stories, and then we look for and present evidence that supports those stories. We build up our ‘story wall’ high, and attract others whose world views and beliefs fit with or support this wall in some way. In other words, we cause our own demise with them.
Soon, we can’t see past our stories, can’t imagine how to move past them, become unaware that there’s even a world beyond them. The wall grows so strong and tall that something huge, shocking, jolting, has to come along to demolish it….or it just stays that way forever, thickening and continuing to cause our own demise.
