We hadn't really thought about it, but it turns out that hippies and Karens have something in common. They both tend to subscribe to the dubious powers of crystals. And this meme ripped from Rick and Morty is more than happy to call them out.
The meme features a scene from the show in which Morty becomes the owner of a crystal that shows its possessor how they will die. Morty becomes obsessed with the stone's vision of his demise, and at one point, utters "I do as the crystal guides." It's the perfect quote for a joke about people who will blindly believe or follow something, and its success is pretty evident from the variety of memes that have come from it.
