We are taught from a young age that consciousness is a product of the brain, but this statement actually deserves to be reinterpreted; the brain is more like a limiter than a producer. Human consciousness itself is broader; it is just filtered by the brain. We can only receive a tiny portion of information through our senses, and the rest is blocked. Under this premise, so-called reality is not just the result of objective existence, but is related to the observer's participation. When a person's attention and state of consciousness change, their perception and experience of reality can also change accordingly. But most people feel powerless because they have been in a system since birth: education, consumption, entertainment, and competition constantly occupy and distract our attention. And attention is actually the most important resource; once it is depleted, a person can only maintain basic functions, making it difficult to actively create and change their own experience. If a person can regain their attention, reduce external distractions, let go of ingrained thinking patterns, and allow consciousness to be in a freer, more focused state, then their perception of the world will change, and many results will follow, appearing as if through a process of "materialization."
