The Law of Mentalism states that everything in the world is created by thought. In other words, nothing exists without a thought. Similarly, all things we experience and see have their origin in our minds. All these things are the result of our thought process. Because of this, humans are capable of almost anything. The Law of Mentalism says that all reality is created within the human mind. It also implies that we can change any aspect of our lives with our minds, including our thoughts and emotions.
