When many of the old saints and sages say, "Your world is a dream. You're living in an illusion," they're referring to this world of the mind and the way we believe our thoughts about reality. When we see the world through our thoughts, we stop experiencing life as it really is and others as they really are. When I have a thought about you, that's something I've created. I've turned you into an idea. In a certain sense, if I have an idea about you that I believe, I've degraded you. I've made you into something very small. This is the way of human beings, this is what we do to each other.
