People naturally try to fit everything into simple categories—things either exist or they don’t. Something is either true or false. But what if reality isn’t that simple? Some of the deepest spiritual traditions in the world, especially those from India and Tibet, suggest that ultimate truth is beyond all the categories we try to place it in. There is a concept in ancient philosophy that challenges how we think about reality—one that says truth is not just beyond "yes" and "no," but also beyond "both" and "neither."
