Beliefs manifest reality. If someone else believes in something, it exists. Everything exists, the universe is infinite.
Disbelief is simply fearing something, not making it non existent. Non existence does not exist.
So suppose I believe you don't believe the things you say. That means you don't believe them.
For one to disbelieve, they must first acknowledge the existence of what they disbelieve in. For you can only have a negative if it's in reference to a positive.
This works the opposite way too. You can only have a positive if it's in reference to a negative. That means all your positive thinking creates bad things in the world. Maybe your thoughts are just an exercise in evil!
allow me to pull a quote from Hesse's
Demian:
"Can you really make someone else think what you want him to?" I asked him.
He informed me willingly, calmly and objectively, in his grown-up fashion.
"No," he said, "that's impossible. You see, no one has free will, even though the pastor implies that. The other fellow can't think what he wants to, nor can I make him think. But it is possible to observe someone carefully, and then you can often say pretty accurately what he's thinking or feeling, and then you can generally foresee what he'll do the next minute. It's quite simple, people just don't know it. Naturally it takes practice. For example, in the butterfly family there are certain night moths with a lot fewer females than males. The moths reproduce just as all animals do; the male fertilizes the female, which then lays eggs. Now, when you have a female of this kind of moth—this has often been tested by biologists—the male moths fly to that female at night, and they fly for hours to get there! Just imagine, hours of flying time! Over miles and miles all these males sense the only female in the vicinity! People try to explain it, but it's hard. It must be some kind of sense of smell or something like that, more or less the way good hunting hounds are able to locate an imperceptible trail and follow it. Understand? There are such things, nature is full of them, and no one can explain them. But now I say: if females occurred as frequently as males among those moths, they wouldn't have that subtle nose! They have it solely because they've trained themselves for it. When an animal or person focuses all his attention and all his willpower on a given objective, he achieves it. That's all there is to it. And it's just the same with what you asked about. Look at a person carefully long enough, and you'll know more about him than he himself does."
...
"But how does that willpower thing work?" I asked. "You say people don't have free will. But then you go on to say that all you need to do is concentrate your willpower on something and you can attain you goal. But that doesn't add up! If I'm not the master of my own will, then I can't focus it on any place I choose to."
He tapped me on the shoulder. He always did that when he was pleased with me.
"I'm glad you're asking that! he said with a smile. "People should always ask questions, they should always entertain doubts. But the matter is very simple. If, for example, a moth of that type wanted to focus its willpower on a star or some such thing, it wouldn't be able to. But it never tries to. It's only out after things that have meaning and value for it, things it needs and absolutely must have. And then it even accomplishes the unbelievable—it develops a magical sixth sense no other animal possesses! We human beings have greater latitude, of course, and more interests than an animal does. But we, too, are confined in a relatively small circle and can't go beyond it. I can fantasize about this and that, I can imagine I just must get to the North Pole, or something like that, but I can only accomplish it and will it strongly enough if the total wish is in my mind, when my being is really completely filled with it. The moment that's the case, the moment you attempt a task that something inside you orders you to do, you'll succeed. And you can harness your willpower like a trusty draft horse. For example, if I were now to try and make our pastor leave off wearing glasses, it wouldn't work. That's only a game. But when I decided firmly, back in the fall, to be moved out of my bench in the front of the room it all went well. Suddenly someone showed up whose name was ahead of mine in the alphabet and who had been ill up to then; and since someone had to yield his seat to him, I was naturally the one who did it, because my will was prepared to seize the opportunity at once."
"Yes, I said, "at the time it struck me as very odd, too. From the moment we got interested in each other, you moved closer and closer to me. But how was it that at first you didn't get to sit right next to me, but started off by sitting on the bench in front of me a few times, right? How was that?"
"It was like this: I myself wasn't clear about what I wanted, when I felt the urge to move away from my first seat. I only knew I wanted to sit farther back. It was my will to come to you, but I had not yet become conscious of it. At the same time your own will pulled along and helped me out. Only when I was sitting in front of you did it occur to me that my wish was only half-fulfilled—I noticed that my desire had really only been to sit next to you."
"But at that time no new boy entered the class."
"No, but that time I simply did what I wanted, and just sat down next to you. The boy with whom I changed places was merely surprised and let me have my way. And the pastor did notice once that a change had taken place—in general, when he has dealings with me, something nags at him secretly, because he knows my name is Demian and it isn't right for me, with my name beginning with D, to be sitting back among the S's! But that doesn't reach his consciousness because my will is set against it and I prevent him time and again from being aware of it. Each time he notices that something is wrong, he looks at me and starts to ponder, the dear man. But I have a simple remedy. Each time, I stare really hard into his eyes. Almost no one can abide that. Everyone gets nervous. If you want to get something out of somebody, and he doesn't get nervous when you unexpectedly stare hard into his eyes, give up. You won't get anything out of him, never! But that's very rare. Actually i know only one person that it doesn't work on for me."
