When we believe what we think, when we take our thinking to be reality, we will suffer. It's not obvious until you look at it, but when we believe our thoughts, in that instant, we begin to live in the world of dreams, where the mind conceptualizes an entire world that doesn't actually exist anywhere but in the mind itself. At that moment, we begin to experience a sense of isolation, where we no longer feel connected to each other in a very rich and human way, but we find ourselves receding more and more into the world of our minds, into the world of our own creation.
